Nomogram-Based Prediction of the Risk of Diabetic Retinopathy: A Retrospective Study

Figure 5

Calibration curves of the DR risk nomogram prediction. The -axis meant the actual diagnosed DR. The -axis meant the predicted risk of DR. The diagonal dotted line meant a perfect prediction by an ideal model. The solid line represented the performance of the training set (a) and validation set (b), which indicated that a closer fit to the diagonal dotted line represented a better prediction.
