A) Receiver operating characteristic (ROC) curve analysis of the CDI risk index in pre-treatment fecal samples collected following 10-fold cross-validation. B) ROC curve analysis of the CDI risk index in pre-treatment fecal samples collected following 10-fold cross-validation of all the held-out samples from the leave-one-out cross-validation analysis. Following the leave-one-out procedure, the ROC curves of each leave-one-out procedure are in blue and the mean ROC curve of all the procedure is in black.
