Prediction model for rapid estimated glomerular filtration rate decline in type 2 diabetes mellitus

Figure 3 Nomogram model and performance evaluation for predicting rapid estimated glomerular filtration rate decline. Nomogram: A prediction model based on 7 independent risk factors. Each factor contributes points according to its regression coefficient (urinary albumin-to-creatinine ratio ≥ 300 mg/g: 100 points; baseline estimated glomerular filtration rate 45-59 mL/minute/1.73 m²: 85 points; hemoglobin A1c ≥ 8.0%: 65 points; serum uric acid ≥ 420 μmol/L: 58 points; systolic blood pressure ≥ 140 mmHg: 52 points; anemia: 47 points; non-use of renin-angiotensin-aldosterone system inhibitors: 43 points). Total points (0-450) correspond to predicted risk probabilities (5%-95%). eGFR: Estimated glomerular filtration rate; UACR: Urinary albumin-to-creatinine ratio; BP: Blood pressure; RAAS: Renin-angiotensin-aldosterone system.
