Kaplan-Meier survival curves for all-cause mortality in three HDL-C groups of LN patients. Log-rank test of three HDL-C groups: P = 0.001. Log-rank test of high HDL-C vs. intermediate HDL-C: P = 0.126; high HDL-C vs. low HDL-C: P = 0.002; intermediate HDL-C vs. low HDL-C: P = 0.017. A two-tailed P-value <0.05/3 was considered statistically significant
