Results: The discriminatory classifier with a panel of four biomarkers determined in the training set could precisely detect 36 of 37 (sensitivity, 97.3%) acute SARS and 987 of 993 (specificity, 99.4%) non-SARS samples. We established a decision tree algorithm consisting of four unique biomarkers for acute SARS in the training set and subsequently validated the accuracy of this classifier by use of a completely blinded test set. To identify the serum biomarkers that could distinguish SARS from non-SARS samples, we used a training set of specimens (37 SARS acute and 74 controls; Tables 1 and 2) and constructed the decision tree classification algorithm using 10 989 peaks [99 peaks ϫ (37 ϩ 74) spectra] of statistical significance identified in the low energy readings (see Materials and Methods). ./cache/cord-273035-sewfb3q8.txt ./txt/cord-273035-sewfb3q8.txt
