Multivariate model of correlates of HIV infection among MSM in Tijuana, Mexico (n=191)

	AOR	p	95% CI
			Lower	Upper
Ever used methamphetamines	4.33	0.01	1.42	13.19
Tested syphilis positive	2.24	0.05	1.02	4.92

CI: confidence interval. Seeds (n=10) have been excluded from the analysis due to non-random sampling. Model tested for clustering at shared recruiter, shared recruitment tree and shared colonia. None of the adjustments provided a better fit for the model; therefore, model is not adjusted for clustering. Also tested with recruiter-level variables for methamphetamine use, HIV status and syphilis status. All recruiter-level variables were not significant and thus not included in the model.

AOR: adjusted odds ratio.
