Sensitivity calculation was determined from the ratio of true positives (HIVpos ARTpos correctly predicted) to total number of modeled HIVpos ARTpos spectra. bSpecificity was calculated from the ratio of true negatives (control samples correctly predicted) to total number of modeled control spectra. cAccuracy was based on the ratio of total number of samples correctly classified to total number of samples predicted. dProbability of a model occurring by chance, satisfied when p<0.05. All calculations are done as widely described in the literature.
