Fig 5. Distribution of cohort follow-up times after treatment from 129 studies collecting data on the efficacy of drugs for treating ascariasis, trichuriasis and hookworm.

Only the first follow-up time is included for studies involving multiple follow ups. Treatment is given on day 0. Details on how follow-up time was calculated when a range of values were possible, are found in S2 Text. The shaded area covers 2–3 weeks after treatment, the window over which the majority of studies included here conducted their first follow-up evaluation. Six cohorts had a variable follow-up time and are not included in the figure.
