*P values obtained from multilevel linear modeling included subject, treatment group, and time as covariates.

†Number of reported illnesses at twice weekly fieldworker visits coinciding with hepcidin measurements (total n = 5113).

‡Number of recorded AEs coinciding with hepcidin measurements ±4 days (total n = 5113).
