  1. All outcomes adjusted for age, sex, marital status, area of residence, level of education and previous VCT use as reported at the later sero-survey round.
  2. α‘Acquired or lost spouse’ was not adjusted for marital status (as this was the outcome).
  3. ΩQuestions related to ‘casual’ rather than ‘high risk’ partners at Sero6, however, the two categories were considered comparable.
  4. #Analyses conducted among those with a spouse at both rounds only.
