DR prediction model for T2DM patients. (a) Clinical parameter-based nomogram integrating age, diabetes duration, HbA1c, albuminuria, and triglyceride to predict 3-, 4-, and 5-year risks of DR development in patients with T2DM. (b) Time-dependent ROC curves of the nomogram showed AUCs for DR prediction models of 3, 4, and 5 years were 0.854, 0.845, and 0.798, respectively. HbA1c: hemoglobin A1c; AUC: area under the ROC curve; ROC: relative-operating characteristic.
