  1. a. Numbers are total that failed testing/total samples tested
  2. b. Includes amodiaquine, mefloquine or sulphadoxine-pyrimethamine
  3. c. Artemisinin-based combination therapy
  4. d. Only 88% of total samples were tested by spectrometry (300 out of 339), since the TruScan spectrometer requires a known good quality version for comparison and for 39 samples this could not be established.
