  1. Reported figures are estimated coefficients (SE) and significance level
  2. All models control for age group, orphanhood, if there is an HIV-positive person in the household, food insecurity, religion, and districts
  3. Sample sizes:
  4. • All outcomes except HIV, HSV-2, number of partners – Total = 2802; KwaZulu-Natal = 1408; Mpumalanga = 1394 (some n's smaller due to missing values)
  5. • HIV and HSV-2 analyses – Total = 2,6,84; KwaZulu-Natal = 1351; Mpumalanga = 1333
  6. • Number of partners among those who had sex by end line – Total = 754; KwaZulu-Natal = 285; Mpumalanga = 469
  7. a Longitudinal analysis. Examined in generalized estimation equation (GEE) model, mixed-effect model and generalized linear latent and mixed model (GLLAMM). Focused on interaction variable between the intervention group and end line. Reported coefficients are from GLLAMM
  8. b Incidence outcomes (ever-sex, ever-pregnant, HSV-2, HSV-2/ever-pregnant) were examined in both survival analysis and logistic regression among those who did not have the outcome at baseline. Focused on the intervention group variable. Reported coefficients are hazard ratios from survival analysis
  9. c Logistic regression. Focused on the intervention group variable. Reported coefficients are odds ratios
  10. d Replaced with missing when the number reported was greater than or equal to 50
