Figure 5. Classification performance on external datasetsROC curves visualizing the classification performance of our 4-gene and 15-gene set models on external microarray datasets in both HIV- and HIV co-infected individuals. Left panels, 4-gene signature; right panels, 15-gene signature. Upper row shows classification performance between TB and healthy in HIV- populations; lower row in HIV co-infected populations. Numbers in parentheses are AUC values. For detailed classification measurements refer to Table 1.
