The ROC scores of the SVM models built from the hERG integrated database (light blue bar), ChEMBL (blue line), GOSTAR (red line), NCGC (green line), and hERGCentral (purple line), using (a) ECFP4, (b) ECFP4 and 72 descriptors as the explanatory variables. The horizontal axis corresponds to the data source of the test set.
