Multiple linear regression model of parasite density at the first febrile malaria episode by different parasite density thresholds^a.

Abbreviations: CL, confidence limit; HbAS, sickle cell trait; NA = not assessed due to lack of individuals with heavy S. haematobium mono-infection in analysis. aEffect of infection status at enrollment on parasite density in log(parasites/µl) using a general linear model with adjustments for age, distance from home to clinic, sickle cell trait, baseline anemia status, and residence in the cluster of high S. haematobium transmission. b1–9 eggs/10 mL urine. c≥10 eggs/10 ml urine. Multiple linear regression model of parasite density at the first febrile malaria episode by different parasite density thresholdsa.
