Kaplan–Meier survival curve. Patients with focal segmental glomerulosclerosis (FSGS) were stratified by albumin permeability (P_alb) ≥0.5 (solid line) and P_alb < 0.5 (dashed line). Kaplan–Meier survival curve showed that patients with who had P_alb ≥ 0.5 progressed to RRT more rapidly. Patients with calculated T-RRT < 3 months (0.25 years) were excluded from this analysis (see text in “Results” section, “latent class regression model” for the rationale for this exclusion)
