Perioperative characteristics of patients undergoing total hip arthroplasty by groups. Data presented as median (interquartile range) for continuous variables, and n (percent of group total) for categorical variables. POD-1/POD-2 = postoperative day 1/2. P values calculated using Mann–Whitney U test (continuous variables) and chi-square test (categorical variables)
