Table 6:

Effect size and Standardized Response Mean (SRM)

	TKA effect size	TKA SRM	THA effect size	THA SRM
H/KOOS pain	2.32	1.92	2.71	2.44
H/KOOS function	1.81	1.61	2.42	2.12
PCS	1.46	1.19	1.93	1.59
MCS	0.19	0.21	0.28	0.30

Effect size and SRM was calculated based on the methods stated in the manuscript: effect size (ES) was calculated as mean change in scores divided by the baseline SD. Standardized response mean (SRM) was calculated as the mean change in the scores divided by the standard deviation (SD) of the changed scores.
