PR was derived from mixed-effects generalized linear model fitting population-averaged panel data, adjusting for the random effects of location. A PR greater than 1.0 indicates an improvement at follow-up. Error bars represent 95% CIs. Definitions of evaluation outcomes are provided in Supplementary Table 5. CRAFFT, Car, Relax, Alone, Forget, Friends/Family, Trouble questionnaire for substance use risk in adolescents. Condom use and effective contraception were asked only in sexually active adolescents in the community setting; effective contraception outcome is shown for females only. ‘Health checks are worthwhile’ was defined as rating 5 on a scale of 1–5 in response to the question ‘How worthwhile do you think getting your health checked is?’. See Supplementary Table 3b,d for further details on each secondary outcome prevalence at baseline and at follow-up, difference in proportions and PR (95% CI).
