Proportion of individuals with clinical manifestations of vivax malaria by parasite density measured by quantitative polymerase chain reaction. Separate univariate logistic regression models were fitted to empirical data from Cahuide (CAH; n=491) and Lupuna (LUP; n=736) using the stats R package: (A) total population of CAH and LUP; (B) age-specific model fits for CAH; (C) age-specific model fits for LUP. Age groups considered were: 0–5 years, 6–15 years, 16–40 years, and 41 years and older. The shaded area indicates the 95% confidence intervals.
