Comparison of HIV infection rates of the adherence and nonadherence groups.

Group	Seroconversions	Person years	Ratea (95% CI)	HRb (95%CI)	P value	AHRc (95%CI)	P value
Totald	20	296.69	6.74 (4.38-10.00)	N/Ae	N/A	N/A	N/A
Nonadherence to HIV testing	12	249.91	4.80 (2.77-7.88)	1.00	N/A	1.00	N/A
Adherence to HIV testing	8	46.77	17.10 (8.80-30.84)	3.48 (1.42-8.54)	.006	3.33 (1.35-8.20)	.009

^aRate is calculated as the number of seroconversions per 100 person years.

^bHR: hazard ratio.

^cAHR: adjusted hazard ratio; multivariate Cox proportional hazards model adjusted for age, condom use behaviors, and other sexually transmitted diseases.

^dA total of 680 men who have sex with men with 2 or more HIV tests were included in this analysis.

^eN/A: not applicable.
