Table 2.

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

	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

^§Differences are presented in effect size and standardized response means (95% confidence interval obtained by bootstrapping).

*p: Type I error of the modified Jacknife test comparing two ES or two SRM.
