Fig. 2From: Mathematical modeling study of school-based chlamydia screening: potential impact on chlamydia prevalence in intervention schools and surrounding communitiesModel-estimated prevalence among sexually active students in intervention schools and in the 15–18 year-old population in the broader communities: baseline (no-screening) and intervention scenarios. Footnote: The model was calibrated to the first positivity estimate available from each program (black dot) with the positivity estimates from later years (white dots) shown for comparison. The intervention start year is marked with a dotted vertical lineBack to article page
