  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 an aqua or nirvana aravani, district, age, literacy, occupation, age at first sex, and residency.
  2. Legend: Table 3 provides proportion of HR-MSM and TGs using condoms with different partners in R 1 and R 2, along with the crude and adjusted odd ratios from multivariate analysis.
