Demographic variables at general university versus dedicated orthopaedic hospital. Demographic variables, such as BMI, sex, diabetes, whether a resident/fellow was scrubbed, positive history of steroid use, and smoking status were examined at the general university versus dedicated orthopaedics specialty hospitals. NR = not reported. For comparisons of age and BMI, Mann–Whitney U nonparametric analysis utilized. For all other variables, X² analysis utilized.
