Elevated Serum Chloride Levels Contribute to a Poor Prognosis in Patients with IgA Nephropathy

Figure 2

Kaplan-Meier renal survival curves for patients with IgA nephropathy (IgAN) according to serum chloride levels. Patients with IgAN were classified into two groups according to serum chloride levels: a low chloride group (<105.4 mmol/L, red line) and a high chloride group (≥105.4 mmol/L, blue line). Log-rank rest revealed that the cumulative renal survival rates in the high chloride group were significantly worse than those in the low chloride group ().
