Change in cognitive testscores over 18 months follow-up in relation to S. japonicum infection-free duration in Filipino school-aged children treated for S. japonicum at enrolment.

WRAML = Wide Range Assessment of Memory and Learning; CI = confidence interval.*Estimates are differences in testscores for varying durations of S. japonicum cure relative to never cured children. Estimated are derived from a repeated measures model adjusted for: time, child age, sex, nutritional status, baseline S. japonicum infection, baseline STH intensity, socioeconomic status, and baseline anemia.**This category includes children that were S. japonicum infected during all periods for which infection was assessed. Some children may not have assessments in all intervals but if they were always S. japonicum positive when infection data is available they are considered never cured.
