Unadjusted and adjusted Poisson regression models with generalized estimating equations, clustered by participant, and robust error variance were used to calculate relative risk and 95% confidence intervals for factors associated with Mycoplasma genitalium infection at each anatomic site tested. Adjusted models included all factors listed in the table. Statistically significant associations (p≤0.05) are shown in bold.
The “bisexual” category of sexual orientation also includes two participants who reported “transgender” and one “queer.”
The “no” category of condom use at last anal sex with a male partner includes one participant who responded “don’t know” when asked about condom use.
Infection status for bacterial STIs was assessed at the same visit and the same anatomic site as the sample collection for Mycoplasma genitalium testing.
