  1. ^Multivariate models were controlled for the following variables for HR-MSM analysis: self-identity, age, literacy, occupation, residency, age at first sex; and the following variables for TG: self-identification as aqua or nirvana aravani, district, age, literacy, occupation, age at first sex, and residency.
  2. Legend: Table 4 provides estimates of HIV prevalence and STI prevalence among HR-MSM and TGs; estimates for HR-MSM provided are overall and district-wise for HIV and syphilis; adjusted odds ratios are provided for change in estimates between IBBA R 1 and R 2.
