Development and validation of a risk score for advanced colorectal adenoma recurrence after endoscopic resection

Figure 1 Receiver operating characteristic curve analysis aimed at identifying the cut-off point for the score. Receiver operating characteristic curve analysis identified the value 5 as the more sensitive and specific cut-off point for the recurrence score.

Figure 2 Ten-fold cross validation error rate. The overall average error rate was 0.12. Red line indicates error rate for recurrence prediction, blue line indicates error rate for non-recurrence prediction, black line the average error rate.
