Prediction Results of OPLS-DA Model Based on FT-IR Spectra Obtained from HIV-Infected Serum and Uninfected Controls

	Sensitivity^a (%)	Specificity^b (%)	Accuracy^c (%) Fischer's probability^d
HIV^posART^pos vs. control	100%	95.24%	95.2% 6.6e-12
HIV^posART^neg vs. control	100%	100%	100% 1.1e-009
HIV^posART^pos vs. HIV^posART^neg	83.33%	100%	89.19% 6.7e-007

^{^a}

Sensitivity calculation was determined from the ratio of true positives (HIV^pos ART^pos correctly predicted) to total number of modeled HIV^pos ART^pos 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.
