Table V.

Effect sizes for total HOOS and its subscales.

	Total HOOS	Stiffness	Pain	ADL	R&S	HR-QL
Pooled variability	21	15	31	15	34	25
Effect size	1.1	1.0	0.7	0.8	1.0	0.6

Pooled variability of both experimental and control group. HOOS, Hip disability and Osteoarthritis Outcome Score HOOS = [(Σ5HOOS subscores)/5]; Stiffness, Symptoms others including stiffness; ADL, Activity limitation in daily living; R&S, Activity limitation in recreation and sport; HR-QL, Hip-related quality of life. Confidence intervals lacking due to non-parametric statistical tests.
