  1. Le Cessie-van Houwelingen-Copas-Hosmer test (P-value): 0.723; AUC: 0.795.
  2. *Three MSM were excluded from initial multivariate model due to missing data in at least one covariate.
  3. **Age was forced a priori the variable age into the multivariate models; Number of male partners, Stimulant use before sex, and currently receiving cART was a confounder and remained in the final multivariate model.
  4. ***Age (years) and Number of male partners within the last 12 months were modeled as restricted cubic spline with three knots (coefficients not shown).
