  1. Abbreviations: Pf = Plasmodium falciparum, Pv = Plasmodium vivax, Pk = Plasmodium knowlesi, Pm = Plasmodium malariae, Po = Plasmodium ovale.
  2. Note: Slides were unavailable for cross-check microscopy for eight patients. Cross-check microscopy was performed on pre-treatment slides for 280 (95%) of 296 patients.
  3. *Includes one post-treatment slide. Parasite counts (according to routine microscopy results) of remaining three patients were 32, 55 and 1574 parasites/μL.
