Contexto
What changed: Entry into weekly drawings to win 100,000 TZS (~US$50) conditional on testing negative for curable STIs, alongside testing, counselling, and bi-weekly safe sex SMS. Comparison: Control group receiving testing, counselling, and safe sex text messages only. Limits: High attrition (~49% lost to follow-up), study was underpowered to detect impacts below 8 percentage points, and client-specific violence was not separated.
