Scores are reported as SMD (95%CI). NE = SMD not estimable; S = reported differences between groups were significant; NS = reported differences between groups were not significant; NR = outcome measure not reported. * scores on the HHS; † scores on the Merle d'Aubigné Hip score; ‡ scores on the WOMAC; § scores on the OHS; ** scores on the physical component of the SF-36; †† scores on the physical component of the SF-12. a Improvement in score. b Gait velocity is used as outcome measure for gait analysis.
* A positive SMD with 95% CI indicates better physical functioning in favor of the study group.
