CovariateOdds Ratio (95% CI)P
Age (years)1.06 (1.02 to 1.10)0.003
Low LVEF3.31 (1.36 to 8.79)0.009

  • Low LVEF, defined as <60%. Heavy proteinuria was defined as 2+ to 4+ on urine dipstick examination. Multiple logistic regression model: n = 1052, adjusted generalized R2 = 0.469, estimated area under the ROC curve = 0.93, and Hosmer-Lemeshow goodness-of-fit test P = 0.26 > 0.05 (degree of freedom = 8).
