S. haematobium infection = Schistosoma haematobium eggs identified by urine filtration; prevalence of heavy-intensity S. haematobium infection = >50 S. haematobium eggs per 10 mL of urine; OR odds ratio (bivariate analysis), aOR adjusted OR (multivariate analysis), CI confidence interval; school attendance = as reported by the head teacher of the respective school; study site = selected public primary schools across an area of 36 districts in Madagascar targeted for control of schistosomiasis with the support of SCI
