  1. Data dictionary:
  2. ID: study subject identification number; start: the start time of the interval (in days); end: the time (in days) at which the event occurs or the time of censoring; episode, the occurrence of malaria episode (yes = 1, no = 0); order: the order of the episodes, which is used only for the PWP-CP model; time: the number of days at risk that is calculated from subtracting end from start variables; treatment: the same malaria treatment given to the patient during each episode; Age (Years): the patients age at enrolment in years; quarter: the resident place or bloc of the patient in the village (old quarter = 1, new quarter = 0).
