Fig 2 New (top) and repeated (bottom) sexual topics discussed, reported by parents and adolescents. Cumulative difference between intervention and control from baseline to each subsequent survey was significant at P<0.001. For new topics, interval differences were not significant. For repeated topics, interval difference for parents was P<0.001 at three months and P=0.003 at nine months; for adolescents, difference was P<0.001 for each interval
