Severe and mild case index model of Enterovirus positive samples. All 20 genes at lowest error rate: 20.83%. A For each individual, a index was calculated to evaluate the risk of severe HFMD disease (Training: M:S = 104:64). The histogram shows the distribution of indices for all individuals. Red means Mild case and blue means severe case. B Receiver operating characteristic curve of the index model. The area under the ROC curve (AUC) of classifier is 0.9. C new samples for test using the index model (Verify: M:S = 10:10). Mild case and severe case were distinguished by the index model (p < 0.01)
