Comparison of the unadjusted PROM scores between women and men 12 months postoperatively

Instruments	Women		Men		Difference	p value	95% CI
	Mean	SD	Mean	SD			Lower	Upper
OHS	42.6	7.1	43.2	7.4	−0.6	0.517	−2.4	1.2
WOMAC pain	94.8	10.2	93.9	13.9	0.9	0.577	−2.2	3.9
WOMAC stiffness	92.3	11.1	92.2	12.9	1.2	0.550	−2.6	4.9
WOMAC function	91.8	11.8	91.5	13.7	0.3	0.835	−2.8	3.5
WOM total score	92.3	10.9	91.7	13.1	0.5	0.732	−2.5	3.5

Higher values indicate better state/condition; PROM = patient-reported outcome measure; CI = confidence interval; OHS = Oxford Hip Score.
