Association between circumcision and HIV risk stratified by anal sexual role/position among men who have sex with men in China

Anal sex role	Circumcised	HIV status (N=1053)^*		Adjusted odds ratio (95% confidence interval)^†	Adjusted odds ratio (95% confidence interval)^†	Adjusted odds ratio (95% confidence interval)^†
Anal sex role	Circumcised	Positive (N=264)	Negative (N=789)	Adjusted odds ratio (95% confidence interval)^†	Adjusted odds ratio (95% confidence interval)^†	Adjusted odds ratio (95% confidence interval)^†
Receptive/versatile	No	177	364	Reference
Insertive	No	76	358	0.40 (0.29, 0.55)		Reference
Receptive/versatile	Yes	9	38	0.54 (0.25, 1.14)	Reference
Insertive	Yes	2	29	0.15 (0.04, 0.65)	0.28 (0.06, 1.41)^‡	0.38 (0.09, 1.64)^#

N=1053 due to missing data on variables of circumcision, HIV status, or anal sex role/position.

^†

Adjusted for age, ethnicity, education, number of lifetime male sexual partners, and Beijing residency.

Compared with circumcised, receptive/versatile-sex subgroup.

Compared with uncircumcised, insertive-sex subgroup.
