Fig. 3From: Individuals living in a malaria-endemic area of Cameroon do not have an acquired antibody response to Plasmodium falciparum histidine-rich protein 2Distribution of MFI for Cameroonian and American adults. MFI values for each antigen for 110 Cameroon and 112 American adults were divided into 9 bins of unequal sizes, in order to expand the lower part of the distribution. The ROC was used to determine optimal cut-offs (vertical dotted lines) for the best overall sensitivity and specificity. Cut-offs: a MSP1-42 = 793 MFI; b MSP2 = 2889 MFI; c MSP3 = 244 MFI; d FV2 = 1345 MFI, e and f no ROC cut‐offBack to article page
