  1. V&P = visual and physical inspection; TLC = thin-layer chromatography.
  2. 1 In the V&P columns, the first represent total failures, including expired samples, and the second only expired samples.
  3. 2 All expired samples were submitted to quality control testing.
  4. 3 For doxycycline, (Brazil) and dihydroartemisinin or piperaquine (Suriname), there was no validated TLC method available at the time and only disintegration was assessed.
