P-values for test for heterogeneity excluded missing or not-tested values. P-values in bold represent significant covariates in the final model.
#
adjusted for site and year.
~
additionally adjusted for all factors that were significant in the final model.
*
Variables were time-updated, i.e. each patient can contribute to more than one category.
IRR, incidence rate ratio; CI, confidence interval; ART, antiretroviral treatment; MSM, men who have sex with men; IDU, injecting drug use.
