  1. (CQ – chloroquine; MF – mefloquine; QUIN – quinine; AMQ – amodiaquine; S – sensitive; R – resistant; 76KT, 86NY, 1042ND and 1246DY – mixed infections; shaded boxes indicate the two cases where there was a significant association between the presence of a particular marker and drug sensitivity: pfcrt 76T/CQR, P = 0.001 and pfmdr1 86N/MFR, P < 0.001)
