Effect of baseline Schistosoma haematobium mono-infection, Plasmodium falciparum mono-infection, and co-infection on first or only malaria episode (with anemia interaction term)a.

Abbreviations: CL, confidence limit; HR, hazard ratio; HbAS, sickle cell trait.aRisk of first or only malaria episode was adjusted for age, distance from home to river, sickle cell trait, anemia status at baseline, residence in the cluster of high S. haematobium transmission, and roof type in the classic Cox proportional hazards model with inclusion of interaction terms between anemia status and the two covariates with S. haematobium infection (anemia*co-infection and anemia*S. haematobium mono-infection).Effect of baseline Schistosoma haematobium mono-infection, Plasmodium falciparum mono-infection, and co-infection on first or only malaria episode (with anemia interaction term)a.
