  1. Only patients who received artemisinin derivative until Day 1 (2 or 3) are included for analysis of Day 1 (2 or 3). Study arms with rectal artesunate were excluded. Positivity rate equal to 0% on Day 2 was carried forward to Day 3 if Day 3 rate was not reported.
  2. ND= There were no patients available with detectable parasitaemia in this category so the OR could not be estimated. P-value = 1.000 for comparison with DHA+PIP treatment (Fisher’s exact test). For the purpose of logistic model this treatment group was merged with all other treatments (not included in the listed categories).
