Receiver operator characteristic curves. A Sensitivity and specificity of classification using total IgG antibodies against only one P. vivax recombinant protein to predict recent infection and B Sensitivity and specificity of classification of recent infection using one of each of the PvRBP2b fragments and another top predictor of recent infection, PvMSP1-19. The receiver operator characteristic curves present the ability of the algorithm to correctly classify individuals as recently infected with P. vivax in the prior 9-month period, or not, based on PCR-detected infections
