  1. Notes: Younger cohort members are expected to be ages 14–18 at endline; older cohort members are expected to be ages 19–23 at endline. All estimates assume alpha of 0.05, power of 0.80, and site fixed effects
  2. aFor each age cohort estimates are based on: 10 sites, 4 clusters per arm per site (40 clusters per arm), and 10 subjects per cluster
  3. bFor each age cohort estimates are based on: 5 sites, 4 clusters per arm per site (20 clusters per arm), and 10 subjects per cluster
  4. cNot powered at 0.80 to detect programme impact
