Effect modification of associations between morbid obesity and death, revision, reoperation, dislocation and all-cause reoperation by sex

Comparison	Adjusted* RR (95% CI); sex
	Women	Men
Death in morbidly obese v. nonmorbidly obese patients	1.39 (1.14–1.70)	1.37 (1.07–1.75)
Revision THA in morbidly obese v. nonmorbidly patients	1.10 (0.79–1.53)	1.43 (0.96–2.13)
Reoperation† in morbidly obese v. nonmorbidly patients	1.59 (1.05–2.40)	0.98 (0.49–1.95)
Dislocation in morbidly obese v. nonmorbidly patients	1.36 (0.87–2.13)	2.38 (1.38–4.10)

CI = confidence interval; RR = risk ratio; THA = total hip arthroplasty.

^*Adjusted for age, sex, socioeconomic status and Johns Hopkins Aggregated Diagnosis Groups.

^†Includes the following surgical procedures: joint incision and drainage, joint synovectomy/débridement, soft tissue (muscle) excision, or replacement of acetabular liner and/or femoral head.
