NOTE: HR, hazard ratio; CI, confidence interval.

Data are the HR, 95% CI, and P-value from Cox proportional hazard regression analyses.

Adjusted for baseline characteristics (age, sex, systolic pressure, serum albumin level, serum creatinine level, urinary protein, use of immunosuppressive therapy).
