The validity ofPfLIgG levels as a proxy measure for the number of malaria episodes during the nonobservation period could be demonstrated by the positive correlation betweenPfLIgG levels and the malaria incidence rates during the 21-month observation period, showing a similar pattern in each of the study arms (Figure 1A)
