MSM, men who have sex with men only; MSW, men who have sex with women only. Men who reported sex with both men and women (n = 35) have been excluded. Missing data comprises ≤6% of data for each variable and has been excluded in calculation of percentages.
OR, unadjusted odds ratio.
Adjusted odds ratios (AOR) were calculated, adjusting for age, idiopathic cases, 100% condom use, and nonanal/nonvaginal sexual activity. Due to the strong inverse correlation between idiopathic cases and C. trachomatis and M. genitalium, two models have been created. Model 1 includes age, idiopathic NGU, 100% condom use, and nonanal/nonvaginal sexual activity variables. Model 2 includes age, C. trachomatis, M. genitalium, 100% condom use, and nonanal/nonvaginal sexual activity variables.
