Ring-stage survival assay (RSA) for artemisinin susceptibility of Plasmodium falciparum isolates and reference clones. Black unfilled and filled circles represent  % survival rate in the ex vivo RSA for Cambodian isolates from Oddar MeanChey (OM) province and in vitro 0−3h RSA for Thai isolates from Pursaron (PL) village in Srisaket province, respectively. Blue squares denote values of ART-sensitive (W2) clones while triangles indicate ART-resistant clones (IPC-4884-purple and IPC-5202-green) obtained from 5 to 7 independent in vitro 0−3h RSA experiments. Bars represent median and interquartile range. Zero values of % survival rate were plotted as 0.001 % in logarithmic scale
