Table 2 Comparative responsiveness estimates of effect size (ES) and standardized response mean (SRM) of the SF-36 and the Harris Hip Score (HHS)

From: Responsiveness and minimal important differences after revision total hip arthroplasty

  HHS - SF-36
  ES (Estimate [95% CI])§ SRM (Estimate [95% CI])§ p(ES)* p(SRM)*
Physical function 6.27 (5.84, 6.69) 10.42 (9.92, 10.92) <0.001 <0.001
Pain function 5.50 (5.05, 5.95) 8.61 (8.21, 9.00) <0.001 <0.001
  1. §Differences are presented in effect size and standardized response means (95% confidence interval obtained by bootstrapping).
  2. *p: Type I error of the modified Jacknife test comparing two ES or two SRM.
