Table 1. Sensitivities and specificities of the ZIKV training model.

Predicted sensitivity [true positive rate (TPR)] and specificity (SPC) of NIRS are shown for cohort 1 samples used in the training set at 4 dpi (n = 61) and 7 dpi (n = 59) and cohort 1 samples that were excluded from the training set (prevalidation) at 4 dpi (n = 65) and 7 dpi (n = 90). Predicted sensitivity and specificity of NIRS are shown for heads/thoraces of cohort 2 samples at 4 dpi (n = 136), 7 dpi (n = 138), and 10 dpi (n = 138) and for abdomens at 4 dpi (n = 136), 7 dpi (n = 138), and 10 dpi (n = 138).
