HAGOS, Copenhagen Hip and Groin Outcome Score; HOOS, Hip dysfunction and Osteoarthritis Outcome Score; HOS, Hip Outcome Score; I2, degree of heterogeneity; MIC, minimal important change; NRS, numeric rating scale; τ2, between-study variance; VAS, visual analogue scale; WMD, weighted mean difference.
∼ Only one study but with two groups; therefore, analysis of τ2 and I2 was possible.
*Between-study variance significant at p<0.05.
