  1. RDT rapid diagnostic test; PCR polymerase chain reaction; Pf Plasmodium falciparum.
  2. a The second round of clinic treatment books in Karen sites were not available to link RDT results to filter-paper blood spots (n = 228). All filter samples were eligible for selection for PCR.
  3. b Cells do not add to 5,934 due to missing age and sex data; percentages may not add to 100% due to rounding.
