Covariate-adjusted estimate (95% CI) of proportion of patients reporting symptoms at least once between day 3 and day 13 by treatment arm

Legend: PQ – primaquine; PQ14 – 14-day course of primaquine; PQ7 – 7-day course of primaquine; Covariate-adjusted site-specific estimated proportions for each treatment arm were generated from logistic regression models adjusted for treatment arm, age, sex, day 0 parasite density and day 0 fever, with all confounders (except treatment arm) set at mean/prevalence values for all trial patients
