MOI of Thai and Cambodian vivax samples detected by HTA versus nPCR assays for Pvmsp1^*

Sample origin	No.	Multiplicity of infection†		P value‡	% Multiclonal
		HTA	nPCR		HTA	nPCR
Thailand	47	3.0 (2–4)	1.1 (1–1)	< 0.001	83%	13%
Cambodia	109	2.9 (2–4)	1.3 (1–1)	< 0.001	84%	25%
Combined	156	2.9 (2–4)	1.2 (1–1)	< 0.001	84%	21%

^*MOI = multiplicity of infection; HTA = heteroduplex tracking assay; nPCR = nested polymerase chain reaction.

^†Reported as mean MOI (interquartile range).

^‡P value comparing MOI of HTA versus nPCR by Wilcoxon rank-sum test.
