Baseline predictors of (A) S. haematobium and (B) S. mansoni infection probability across 29 co-endemic schools in Mali (n = 2477 children).

Parameter estimates (on the logit scale) are from binomial mixed models. χ2 and p values are from likelihood ratio tests comparing models with and without the term in question. Age was mean-centred in both analyses. ‘ref’ indicates the reference level of each factor.
