Cox regression models for renal outcome of the doubling of the baseline serum creatinine.

Data are reported as hazard ratio (HR) and 95% confidence interval (CI).Model 1: age, sex, presence of gross hematuria, mean arterial blood pressure, eGFR, proteinuria, treatment, and serum C3 levels.Model 2: age, sex, presence of gross hematuria, mean arterial blood pressure, eGFR, proteinuria, treatment, and pathologic findings.Model 3: Model 2+serum C3 levels.Model 4: Model 3+BMI, total cholesterol, and serum albumin.eGFR, estimated glomerular filtration rate; PCR, protein-to-creatinine ratio.
