Short and mid-term outcomes and functional results in metal-on-metal hip resurfacing arthroplasty at 5 years follow-up: the Spanish experience

Table 2 Limb asymmetry pre-surgery and 3-months post-surgery

Asymmetry	Mean	SD	CI 95%	Median	Min	Max	n	Missing data	p-value
Pre-surgery	0.86	0.44	0.77–0.95	0.8	0.5	2.5	90	55	0.001
3-months post-surgery (cm)	0.55	0.38	0.46–0.65	0.5	0	2	64	81	Ref.

The p-value corresponds to a comparison between the asymmetry values pre-surgery and post-surgery using the Wilcoxon Test
