Aim: To prospectively determine whether social deprivation has an effect on the level of disability at presentation and the outcome from total knee replacement (TKR). Method: A prospective outcome study was carried out between 1992 and 1996, recruiting over 2500 total knee replacements. All patients were assessed preoperatively and at 3 and 12 months postop using the Knee Society (KS) scores for clinical evaluation and the Nottingham Health Profile (NHP) to measure general health status. The Townsend Score was used as the index of social deprivation and was calculated for each patient on the basis of their address. Results: There was no significant difference between either the Knee Society or NHP scores at baseline and the Townsend Score. This indicated that social deprivation has no effect on the level of the knee arthritis immediately prior to joint replacement, both in terms of patient disability and health status. There was also no significant difference between either the Knee Society or NHP scores postoperatively and the Townsend Score. This indicated that social deprivation has no effect on the outcome from knee replacement. Conclusion: This study shows that social deprivation has no significant effect on the level of disability at presentation and the outcome from total knee replacement. This is contrary to previously published reports which have shown worse outcomes in more deprived patients

Background. Reduced bone mineral density is recognised as a risk factor for hip fractures and fragility fractures in general. Vitamin D is important in maintaining healthy bone mineral levels and can therefore affect risk of hip fracture. We investigated the correlation between vitamin D levels and bone mineral density, as well as fracture type, in neck of femur fractures and also assessed the relationship of vitamin D and social deprivation. Method. We included all patients admitted to our department, with a neck of femur fracture over one year (October 2013 to October 2014). We analysed vitamin D levels for all patients during admission and compared these to bone mineral density scores, based on DEXA scan results; hip fracture type & comminution, based on admission radiographs; and levels of social deprivation, based on the patient's address. Results. In total 360 patients were admitted over the study period, with a neck of femur fracture, of which 298 had vitamin D assessed and 76 had DEXA scans. Of these cohorts, 71% were found to be vitamin D deficient and 7% had osteoporosis. No significant correlation was found between vitamin D scores and bone density, or with level of vitamin D deficiency and fracture type or comminution. A significant correlation was however identified, between low vitamin D levels and decreasing levels of social deprivation (R=0.11, p=0.04). Conclusion. No relationship was identified between vitamin D levels and hip fracture type, suggesting that vitamin D cannot be used to predict patients at risk of more comminuted fractures. Although no relationship was also identified for bone mineral density and vitamin D, this may be because the sample size of DEXA scans was relatively small. Interestingly the relationship between vitamin D and social deprivation was the reverse of what was expected and suggests that affluent individuals may be at greater risk of low vitamin D

Introduction. This study investigates the epidemiology of proximal radial fractures and potential links to social deprivation. Patients and Methods. From a prospective database we identified and analysed all patients who had sustained a fracture of the radial head or neck over a one year period. The degree of social deprivation was assessed using the Carstairs and Morris index. The relationship between demographic data, fracture characteristics and deprivation categories was determined using statistical analysis. Results. Two hundred and ninety radial head (n=203) and neck (n=87) fractures were diagnosed with a mean age of 44.3years (13–94). There was no significant difference with regards age or gender predominance when comparing radial head and neck fractures directly. The mean age of males was significantly younger when compared to females for radial head (p<0.001) and neck (p<0.001) fractures, but with no gender predominance seen. Associated injuries (n=25) were related to increasing age (p=0.006), radial head fractures (p=0.003) and increasing fracture complexity according to the Mason classification (p<0.001). Social deprivation was related to the mean age at the time of fracture and the mechanism of injury (p<0.05 for both). Conclusions. Proximal radial fractures are frequently fragility fractures affecting older females and assessment for osteoporosis is recommended. Complex radial head fractures require thorough investigation for the presence of associated injuries

Open or closed fracture of the tibial shaft is a common injury. There is no long-term outcome data of patients after tibial shaft fracture utilising modern treatment methods. This study assessed pain and function of 1509 consecutive patients with a tibial shaft fracture at 12–22 years following injury. Secondary outcomes included: effect on employment, effect of social deprivation, necessity for hardware removal and comparative morbidity following fasciotomy. Prospective study of 1509 consecutive adult patients with a tibial shaft fracture (1990–1999) at a high-volume trauma unit. 1034 were male, and the mean age at injury was 40 years. Fractures were classified according to AO, and open fractures graded after Gustillo and Anderson. Time to fracture union, complication rate, hardware removal and incidence of anterior knee pain were recorded. Employment and assessment of social deprivation were detailed. Function was assessed at 12 to 22 years post injury using the Short Musculoskeletal Functional Assessment and Short Form 12 questionnaires. 87% of fractures united without further intervention. Social deprivation was associated with higher incidence of fracture and poorer functional and economic outcomes. 11.5% patients underwent fasciotomy which correlated with poorer long-term outcome. Tibial shaft fracture had high mortality in the elderly. At long-term follow-up 25% of patients have anterior knee pain and 20% ankle discomfort after IM nailing. This is the largest and longest study assessing functional and economic outcomes of tibial shaft fracture. This is the first paper to describe ankle pain following tibial IM nailing at long-term follow-up

Mortality following hip arthroplasty is affected by a large number of confounding variables each of which must be considered to enable valid interpretation. The aim of this study was to establish whether it is possible to determine a true cause-and-effect relationship between the risk of mortality and data that are routinely collected by the NJR and to establish the degree to which variation in the mortality rate could be explained by each variable. Relevant variables available from the 2011 NJR data setwere included in a Cox model. We carried out two analyses:. Firstly, we conducted an analysis of data collected from the NJR data set used in preparation of the NJR's 8th Annual Report (2011) looking for an association between the variables collected and the risk of mortality. Secondly, as social deprivation is also known to influence mortalityrates but is not routinely collected as part of the NJR data set, a further analysis was performed which included social deprivation data derived from partial postcodes. Mortality rates in hip arthroplasty patients were lower than in the age matched population across all hip types. Age at surgery, ASA grade, diagnosis, gender, provider type, hip type and lead surgeon grade all had a significant effect on mortality. Schemper's statistic showed that only 18.98% of the variation in mortality was explained by the variables available in the NJR data set. It is inappropriate to use Registry data to study an outcome affected by a multitude of confounding variables when these cannot be adequately accounted for in the available data set

Our knowledge of the incidence of scoliosis and scoliosis surgery is based on a few small scale studies. The National Health Service (NHS) in the United Kingdom has long collected data on hospital based activity. We have used a five year English database (1998–2002) of hospital admission statistics to study age-adjusted admission rates for scoliosis (code M41 in the International Classification of Diseases, 10th revision) and for two scoliosis surgery codes (V41 ‘instrumental correction of deformity of spine’ and V42 ‘other correction of deformity of spine’ (the latter includes ‘anterolateral release of spine for correction of deformity’). Results: Three thousand, seven hundred and eighty three patients (2533 females and 1240 males) aged 5–29 years had diagnosis M41 recorded over the five year sample period. Most of the patients were teenagers. 971 (males and females) of these had operation V41 and 1212 had V42, it is likely that the vast majority of these cases had idiopathic scoliosis. We made regional maps based on age-adjusted admission rates/100000 population. Admission rates varied from 5.75/100000 (95% confidence intervals x to y) in London to 2.8/100000 (x to y) in the Yorkshire-Humberside region. Interpretation: There was wide geographical variation in admission rates. We considered 5 hypotheses:. Social deprivation – we were able to study this, and admission rates appeared independent of social deprivation. Availability of spine surgeons – this may be an explanation, but not very convincing. Scoliosis surgery is concentrated in 15 centres that do not obviously link with the variations we found. Variation in decision making about referral and/or treatment (by general practitioners, patients or surgeons). This is possible, but cannot be studied using our data. Regional genetic variation. Some of our maps were consistent with concepts of local biological variation, but are not very convincing. Incomplete or inaccurate coding in routine hospital statistics. Cannot be studied using our database alone. Conclusion: There is wide variation in recorded rates of diagnosis and surgical treatment without obvious explanation. It might be possible to study clinical case notes, identified from the statistical database, to check whether variation is simply attributable to unreliability of coding. To determine whether there may be a genetic explanation for the geographical variation found by us, the possibility could be explored of comparing the scoliosis maps with other maps of genetic profiles of the English population

Socially deprived patients face significant barriers that reduce their access to care, presenting unique challenges for orthopaedic surgeons. Few studies have investigated the outcomes of surgical fracture care among those socially deprived, despite the increased incidence of fractures, and the inequality of care received in this group. The purpose of this study was to evaluate whether social deprivation impacted the complications and subsequent management of marginalized/homeless patients following ankle fracture surgery. In this retrospective, population-based cohort study involving 202 hospitals in Ontario, Canada, we evaluated 45,444 patients who underwent open reduction internal fixation for an ankle fracture performed by 710 different surgeons between January 1, 1994, and December 31, 2011. Socioeconomic deprivation was measured for each patient according to their residential location by using the “deprivation” component of the Ontario Marginalization Index (ON-MARG). Multivariable logistic regression models were used to assess the relationship between deprivation and shorter-term outcomes within 1 year (implant removal, repeat ORIF, irrigation and debridement due to infection, and amputation). Multivariable cox proportional hazards (CPH) models were used to assess longer-term outcomes up to 20 years (ankle fusion and ankle arthroplasty). A higher level of deprivation was associated with an increased risk of I&D (quintile 5 vs. quintile 1: odds ratio (OR) 2.14, 95% confidence interval (CI), 1.25–3.67, p = 0.0054) and amputation (quintile 4 vs. quintile 1: OR 3.56, 95% CI 1.01–12.4, p = 0.0466). It was more common for less deprived patients to have their hardware removed compared to more deprived patients (quintile 5 vs. quintile 1: OR 0.822, 95% CI 0.76–0.888, p < 0.0001). There was no correlation between marginalization and subsequent revision ORIF, ankle fusion, or ankle arthroplasty. Marginalized patients are at a significantly increased risk of infection and amputation following operatively treated ankle fractures. However, these complications are still extremely rare among this group. Thus, socioeconomic deprivation should not prohibit marginalized patients from receiving operative management for unstable ankle fractures

Risk of revision following total knee replacement is relatively high in patients under 55 years of age, but little is reported regarding non-revision outcomes. This study aims to identify predictors of dissatisfaction following TKR in patients younger than 55 years of age. We assessed 177 TKRs (157 consecutive patients) from 2008 to 2013. Data was collected on age, sex, implant, indication, BMI, social deprivation, range of motion, and prior knee surgery in addition to Oxford Knee Score (OKS) and SF-12 score. Postoperative data included knee range of motion, complications, and OKS, SF-12 score and satisfaction measures at one year. Overall, 24.9% of patients (44/177) were unsure or dissatisfied with their TKR. Significant predictors of dissatisfaction on univariable analysis (p<0.05) included: Kellgren-Lawrence grade 1/2 osteoarthritis; indication; poor preoperative OKS; postoperative complications; and poor improvements in OKS and pain component score (PCS) of the SF-12. Odds ratios for dissatisfaction by indication compared to primary OA: OA with previous meniscectomy 2.86; OA in multiply operated knee 2.94; OA with other knee surgery 1.7; OA with BMI>40kgm-2 2; OA post-fracture 3.3; and inflammatory arthropathy 0.23. Multivariable analysis showed poor preoperative OKS, poor improvement in OKS and postoperative stiffness, particularly flexion of <90°, independently predicted dissatisfaction (p<0.005). Patients coming to TKR when under 55 years of age differ from the ‘average’ arthroplasty population, often having complex knee histories and indications for surgery, and an elevated risk of dissatisfaction

Background. Vitamin D deficiency may increase predisposition to a number of paediatric orthopaedic conditions and the prevalence of vitamin D deficiency is increasing in children in developed countries. The aim of this study was to determine the epidemiology of vitamin D deficiency and insufficiency in children presenting to a regional paediatric orthopaedic service. We also examined the relationships between vitamin D status, social deprivation and ethnicity. Methods. Individuals, age < 18 years, presenting to the regional paediatric orthopaedic service at Southampton, UK from 2008 to 2010 were investigated. Deprivation index scores were calculated from indices of deprivation. Results. 187 children (97 male, 90 female, mean age 7.1 years) underwent serum 25-(OH) D level measurement. 82% were white British and 11% of Asian ethnicity. The calculation of the total depravation index for the whole cohort showed 34 (18%) of subjects were in quartile 1 (least deprived), 54 (29%) in quartile 2, 49 (26%) in quartile 3 and 50 (27%) in quartile 4 (Most deprived). 60 (32%) had vitamin D insufficiency with 25-(OH) levels < 50nmol/l and 15 (8%) had vitamin D deficiency. No relation ship was identified between vitamin D level and social depravation score. Conclusions. There is a need for awareness of the prevalence of vitamin D deficiency in the paediatric orthopaedic population presenting with bone pain and lower limb deformity before commencing ‘observation or orthopaedic surgical treatment’

Background. There is a lack of information on the independent preoperative predictors of perioperative mortality, including the influence of previous stroke and acute coronary syndromes (myocardial infarction + unstable angina, ACS). Previous studies have grouped variables under the umbrella term “ischaemic heart disease”. In this study, we investigated the influence of vascular risk factors separately. Methods. The Hospital Episode Statistics database was analyzed for elective admissions for total hip (THR) and total knee (TKR) replacements between 2004 and 2009. Independent preoperative predictors of perioperative outcome were identified from admission secondary diagnosis codes. Perioperative mortality was defined as 30-day in-hospital death. Logistic regression analysis was used to identify independent predictors of 30-day mortality. Data was adjusted for age, social deprivation and Charlson co-morbidity score. Results. 414,985 THRs and TKRs were performed in the study period. There were 829 deaths within 30 days (0.2%). Previous ACS (OR: 1.73 [1.33 to 2.25]) and stroke (OR: 1.64 [1.02 to 2.65]) predicted 30-day mortality. ACS (OR: 3.81 [1.55 to 9.34]) within six months of THKR surgery was associated with increased odds of perioperative mortality. The effect of ACS persisted up to 12 months (OR: 1.99 [1.02 to 3.88]). Renal failure, liver disease, heart failure, peripheral vascular disease and non-atrial fibrillation arrhythmia also increased the odds of mortality. Discussion. Previous stroke and ACS increase the odds of perioperative mortality, together with several other vascular risk factors. Within 12 months of ACS, risk of mortality is significantly elevated. Elective surgery should be avoided in this period

Introduction:. Calcaneal fractures are rare but debilitating injuries assumed to affect particular demographic sub groups. This study aimed to relate epidemiological factors (age, gender, smoking status and social deprivation scores) to the incidence of calcaneal fractures requiring operative fixation over a 10-year period. Methods:. Data (age, gender and smoking status) was extracted from a prospective trauma database regarding calcaneal fractures between September 2002 and September 2012. The Rank of Index of Multiple Deprivation (IMD) scores was collated for each patient and data sub-stratified in 20% centiles. 2010 National Census Data was used to formulate patient subgroups and incidences. Resulting data was subjected to statistical analysis through calculation of relative risk (RR) scores with 95% confidence intervals (95% CI). Results:. 101 calcaneal fractures in 95 patients that underwent operative fixation were identified. 3 open fractures in 3 patients were excluded. In males, the annual incidence of calcaneal fractures requiring operative fixation was 5.10 per 100,000 compared to 1.25 per 100,000 in females (RR 1.60, 95% CI 1.45–1.77). The mean age in males was 36.8 years with a peak incidence between 20–29 years old. The mean age of females was 42.5 years with a peak incidence between 30–39 years old. In females, there was a more even spread throughout all ages with a gradual increase in incidence towards post-menopausal ages. 54 (55.1%) fractures requiring operative fixation occurred in smokers compared to 44 (44.9%) in non-smokers, (RR 2.00, 95% CI 1.39–2.88). Rank of IMD scores revealed 34.0 % of all fractures occurred in the top 20% (RR 1.7, 95% CI 1.28–2.26) most deprived areas and 58.5% of fractures in the top 40% most deprived areas. Conclusions:. This study indicates that male gender, smoking status and high rank of multiple deprivation scores are independent characteristics associated with calcaneal fractures requiring operative fixation

Background: The purpose of this study was to investigate the relationship between neck pain and upper limb disability. Methodology: This was a secondary analysis of neck pain patients participating in an RCT comparing usual physiotherapy with graded exercise treatment, to investigate the correlation between baseline neck pain and baseline upper limb disability. 151 neck pain patients from High Wycombe, Nottingham, Grimsby and Hull participated in the study. The measure used to assess baseline neck pain/disability was the Northwick Park Neck Pain Questionnaire (NPQ). The measure of baseline upper limb disability was the Disabilities of Arm, Shoulder, Hand (DASH). A range of variables were also measured at baseline as potential confounding variables. These included pain self efficacy, anxiety, depression, fear avoidance beliefs, coping strategies, age, gender, current smoking status, material and social deprivation and activity level. The measures were validated self administered questionnaires. Results: Pair wise analysis revealed a strong positive correlation between NPQ score and DASH score (Pearsons’ r=0.799, p< 0.001 (2 tailed), n=142). Stepwise linear regression indicated that increased severity of upper limb disability was predicted by two baseline variables: higher NPQ scores (B=0.743) and lower pain self efficacy scores (B= – 0.489) {Adjusted R2=0.708; n=100, p< 0.001}. After adjusting for potential confounding variables there remains a strong positive association between NPQ score and DASH score. Conclusions: Patients presenting with high levels of neck pain may also have high levels of upper limb disability. Upper limb disability may need to be assessed and addressed as part of the neck management process

Aims. We aimed to examine the true incidence of DDH in our area, and to investigate both known and unknown risk factors for the condition. Methods. Data were prospectively recorded on all live births in the Exeter area from January 1998 to December 2008. The data included the baby's gestational age, sex, demographic details of parents, maternal age and parity, geographic and socioeconomic data, mode of presentation and delivery, and family history of DDH. Data were also collected prospectively on all treated cases of DDH (Graf 2c and above) for the same period. Using the population live birth data as controls, odds ratios (OR) and confidence intervals were calculated. Results. The incidence of DDH in our area was 4.9 per 1000 live births. Although this might have been influenced by selective ultrasound screening, our records show that 74% of our cases had a Graf 3 or Graf 4 hip or presented late, and thus they would arguably have presented with or without screening. The remaining 26% had significant dysplasia (Graf 2c) with or without instability. Female sex (OR 7.3, 4.5-10.1), primiparity (OR 3.6, 2.3-5.6), positive family history (OR 12.6, 8.9-17.8) and breech presentation (OR 8.6, 6.1-12.1) were confirmed as risk factors for DDH. Caesarian section was protective in both cephalic (reduction in OR 0.5) and breech (reduction in OR 2.3) presentations. Postmaturity increased the chance of DDH (OR 2.7, 1.9-3.9). Certain postcodes also had significantly higher incidences (up to 11 per 1000 births), and these areas scored higher on an index of social deprivation. Birth weight, head circumference, and maternal blood group had no significant effects. Conclusions. Incidence in our area was higher than is usually quoted. Our data suggest that there are geographical variations in the condition's incidence. We identified novel risk factors that warrant further investigation

Funding for the health service is limited and this inevitably leads to rationing. However, the allocation of funding to different specialities and clinical areas often has no rational basis. The aim of this study was to evaluate the health status of patients on the orthopaedic waiting list. The SF-36 was used as a postal questionnaire and sent to all adult patients on the elective orthopaedic waiting list at our hospital. Demographic data was collected and patients were grouped by intended operation. The health domains of the SF-36 were adjusted for demographic variables and compared to population norms using non-parametric statistical methods. The SF-36 was sent to 1586 patients and 1155 responded (73%). Analysis was undertaken for hip replacement (n=194), knee replacement (n=291), knee arthroscopy (n=232), foot and ankle (n=147) and cruciate ligament reconstruction (n=46). All diagnostic groups had significantly worse (p< 0.05) scores for all domains of health when compared to population norms. Patients awaiting joint replacement had worse disability (p< 0.001) than other groups, particularly for pain and physical function. Patients over 40 years awaiting arthroscopy had disability approaching these levels and those awaiting ACL reconstruction had poor physical function. In general, patients awaiting foot or ankle surgery had better health than other diagnostic groups but still had significant reductions when compared to normal. Health scores were not related to the Townsend index for social deprivation, indicating equity of access within the health service. Patients awaiting hip and knee replacement have worse health than others on the waiting list. The SF-36 could be a useful tool if priority on waiting lists were to be determined by pain and disability rather than waiting time

We examined the effect of age, gender, body mass index (BMI), medical co-morbidity as represented by the American Society of Anaesthesiologists (ASA) grade, social deprivation, nursing practice, surgical approach, length of incision, type of prosthesis and duration of surgery on length of stay after primary total hip arthroplasty (THA). Data was collected on 675 consecutive patients in a regional orthopaedic centre in South West England. The length of stay varied from 2 to 196 days and was heavily skewed. Data were therefore analysed by non parametric methods. To permit comparison of short with protracted length of stay, data were arbitrarily reduced to 2 groups comprising 2 to 14 days for short stays and 15 to 196 for long. These data were analysed by Chi-squared and Fisher’s exact test in univariate and by Logistic regression for multivariate analysis. The mean length of stay was 11.4 days, an over-estimate compared to the median length of stay of 8 days which more correctly reflects the skewed nature of the distribution. 81.5% of patients left hospital within 2 weeks, 13.6% within 2 and 4 and 4.9% after 4. On univariate analysis age above 80 years, age between 70 and 79 years, Body Mass Index > 35, ASA grades 3 and 4, transgluteal approaches, long incisions, cemented cups and prolonged operations were associated with longer stays. On multivariate analysis, age above 80, age between 70 and 80, ASA grades 3 and 4, prolonged operations and long incisions were highly significantly associated with hospital stay of over 2 weeks. This is the first study to record all the published variables associated with length of stay prospectively and to subject the data to multivariate analysis. Prolonged stay after THA is pre-determined by case mix but slick surgery through limited incisions may reduce the length of admission

Aims

The overall aim of this study was to determine the impact of deprivation with regard to quality of life, demographics, joint-specific function, attendances for unscheduled care, opioid and antidepressant use, having surgery elsewhere, and waiting times for surgery on patients awaiting total hip arthroplasty (THA) and total knee arthroplasty (TKA).

Methods

Postal surveys were sent to 1,001 patients on the waiting list for THA or TKA in a single Northern Ireland NHS Trust, which consisted of the EuroQol five-dimension five-level questionnaire (EQ-5D-5L), visual analogue scores (EQ-VAS), and Oxford Hip and Knee Scores. Electronic records determined prescriptions since addition to the waiting list and out-of-hour GP and emergency department attendances. Deprivation quintiles were determined by the Northern Ireland Multiple Deprivation Measure 2017 using postcodes of home addresses.


Aims

Delirium is associated with adverse outcomes following hip fracture, but the prevalence and significance of delirium for the prognosis and ongoing rehabilitation needs of patients admitted from home is less well studied. Here, we analyzed relationships between delirium in patients admitted from home with 1) mortality; 2) total length of hospital stay; 3) need for post-acute inpatient rehabilitation; and 4) hospital readmission within 180 days.

Methods

This observational study used routine clinical data in a consecutive sample of hip fracture patients aged ≥ 50 years admitted to a single large trauma centre during the COVID-19 pandemic between 1 March 2020 and 30 November 2021. Delirium was prospectively assessed as part of routine care by the 4 A’s Test (4AT), with most assessments performed in the emergency department. Associations were determined using logistic regression adjusted for age, sex, Scottish Index of Multiple Deprivation quintile, COVID-19 infection within 30 days, and American Society of Anesthesiologists grade.

Aims

The primary aim was to assess whether preoperative health-related quality of life (HRQoL) was associated with postoperative mortality following total hip arthroplasty (THA) and knee arthroplasty (KA). Secondary aims were to assess whether patient demographics/comorbidities and/or joint-specific function were associated with postoperative mortality.

Methods

Patients undergoing THA (n = 717) and KA (n = 742) during a one-year period were identified retrospectively from an arthroplasty register. Patient demographics, comorbidities, Oxford score, and EuroQol five-dimension (EQ-5D) were recorded preoperatively. Patients were followed up for a minimum of seven years and their mortality status was obtained. Cox regression analysis was used to adjust for confounding.

Aims

Tuberculosis (TB) is one of the biggest communicable causes of mortality worldwide. While incidence in the UK has continued to fall since 2011, Bradford retains one of the highest TB rates in the UK. This study aims to examine the local disease burden of musculoskeletal (MSK) TB, by analyzing common presenting factors within the famously diverse population of Bradford.

Methods

An observational study was conducted, using data from the Bradford Teaching Hospitals TB database of patients with a formal diagnosis of MSK TB between January 2005 and July 2017. Patient data included demographic data (including nationality/date of entry to the UK), disease focus, microbiology, and management strategies. Disease incidence was calculated using population data from the Office for National Statistics. Poisson confidence intervals were calculated to demonstrate the extent of statistical error. Disease incidence and nationality were also analyzed, and correlation sought, using the chi-squared test.
