FIGURE 2:
Kaplan–Meier survival curves for the event-free survival of CKD progression (defined by α ≥25% decrease in eGFR from baseline and worsening of eGFR categories according to KDIGO guidelines) in (a) the whole cohort, (b) patients with eGFR ≥45 mL/min/1.73 m2 and (c) patients with eGFR 15–44mL/min/1.73 m2. (a) Log-rank test statistics = 58.64, P < .001; (b) log-rank test statistics = 1.59, P = .207; (c) log-rank test statistics = 12.59, P = < .001.
