  1. All values were calculated using the results of the nested PCR as a standard
  2. aSome cases flagged as “MI-RBC Abn” in were excluded from the calculation
  3. bThe values regarding the P. falciparum detection ability of the T1 band were calculated
  4. cThe values regarding the Pan-parasites detection ability of the T2 band were calculated
