Table 2 Comparison of infection prevalences among 810 participants, stratified by control and intervention communities during baseline and follow-up surveys. Logistic regressions were used to derive odds ratios for comparison of prevalences of control and intervention communities at baseline and follow-up. The prevalence reduction was calculated as baseline prevalence minus follow-up prevalence for control and intervention communities separately

From: Effect of an integrated intervention package of preventive chemotherapy, community-led total sanitation and health education on the prevalence of helminth and intestinal protozoa infections in Côte d’Ivoire
