Silent diabetic nephropathy

Figure 1 Renal survival. A: Depending on glomerular classification. For renal survival analysis using the Kaplan-Meier method, histopathological classes I, IIa and IIb were grouped together as there were insufficient cases for separate analysis. The median renal survival in class I/IIa/IIb was 4.2 years (95%CI: 1.8-6.6), in class III, it was 3.4 (95%CI: 0.6-6.2), and in class IV, it was 0.4 (95%CI: 0-1.2). We found statistically significant differences (P = 0.009) when comparing class IV with the other classes and also when comparing class III to classes I and IIa-IIb; B: In silent and non-silent diabetic nephropathy. Renal survival of patients with silent and non-silent diabetic nephropathy (DN) was compared. The median of renal survival in patients with silent DN was 5.2 years (95%CI: 1.1-9.4) and 1.2 years (95%CI: 0.5-1.8) in cases of patients with non-silent DN (P = 0.009).
