  1. a = The estimates shown here are weighted estimates.
  2. b = The reference for each of the estimate is Round 1 of the IBBA. Thus, for consistent condom use with a regular male partner, the interpretation will be as follows: subjects in Round 2 of IBBA were significantly more likely to report consistent condom use with a regular male partner, compared with those in Round 1 of IBBA (OR: 1.90, 95% CI: 1.01 – 3.58).
  3. c = The models were adjusted for district of interview, self-reported sexual identity, current age, literacy, place of residence, sex outside place of residence, and main source of income.
  4. *p = 0.05, ** p < 0.01.
  5. † = Any person reactive on RPR and TPHA.
  6. †† = The titre obtained on RPR was used to measure this variable.
