Survival until progression by tertiles of the estimated GFR six-variable Modification of Diet in Renal Disease (eGFR-MDRD6)–based Toronto Risk Score without proteinuria calculated during the first 6 months of follow-up. The eGFR-MDRD6 risk score was calculated as the logistic function of 1.26−0.3 · ΔeGFR-MDRD6−0.05 · eGFR-MDRD6 at baseline. For the Kaplan–Meier plot, follow-up duration has been truncated at 60 months. The eGFR-MDRD6 risk score was <0.10 for the low-risk tertile (solid line), 0.10–0.30 for the medium-risk tertile (dots and dashes), and >0.30 for the highest-risk tertile (long dashes).
