  • a Gender, ethnicity, proteinuria, and MAP at onset as well as immunosuppressive therapy were not predictive of renal survival by univariate analysis. CI, confidence interval.

  • b BMI divided into three categories low (BMI <20), normal (BMI 20 to 27), and high (BMI > 27).

  • c Expressed as a time-dependent variable. For PR and CR, the multivariate analysis used clearance at time of remission.
