Figure 1. ROC curve for artificial neural networks and logistic regression analysis in identifying SDI≥1 and SDI≥5.

Figure 1

The ANN AUC is significantly superior to LR AUC both in identifying SDI≥1 (p<0.01) (A) and SDI≥5 (p<0.001) (B). ROC: Receiver operating characteristic, SN: sensitivity, SP: specificity. ANNs: artificial neural networks; AUC: area under the curve; LR: logistic regression analysis.
