Development and Validation of a Nomogram to Predict Type 2 Diabetes Mellitus in Overweight and Obese Adults: A Prospective Cohort Study from 82938 Adults in China

Figure 4

Calibration curves of the nomogram prediction in the study. The observed T2DFS is shown compared with the nomogram at 3 years (a) and 5 years (c) using the training set and validation set (b and d), respectively. Notes: the x-axis represents the predicted T2DFS probability. The y-axis represents the actual identified subjects with T2DFS. The diagonal gray line represents a perfect prediction by an ideal model. The solid line represents the performance of the nomogram, of which a closer fit to the diagonal gray line represents a better prediction.
