The recent evaluation by Jemmott et al1 is a robust contribution to the literature on abstinence-based approaches for preventing sexually transmitted infections. Compared with past studies in our systematic reviews of abstinence-based interventions,2,3 this trial had remarkable strengths. It was the second trial to evaluate both abstinence-only and comprehensive programs and the first to find a significant long-term benefit of an abstinence-only approach. Its rigorous methods compare favorably with previous studies.
