  1. Multivariate logistic regression analysis.
  2. n = 56482 (18 cases with missing data for the sex variable); r2 = 0.095; p < 0.0001; C-Statistic: 0.745; p(Hosmer-Lemeshow) = 0.006. Non-significant variables: Type of surgery (arthroplasty vs. internal fixation), time to surgery (early vs. delayed). OR: odds ratio; 95CI: 95% confidence interval.
