Figure 2

The Kaplan-Meier estimates for the survival functions of HD patients according to outcomes of PAD status during observation period. The triangle (△), square (□), and circle (○) on curves indicated censoring cases for prevalent PAD cases initially, incident PAD cases during follow-up, and non-PADs throughout follow-up.

(a) Survival from CVD mortality ( value of log-rank test = 0.0103)

(b) Survival from all-cause mortality ( value of log-rank test = 0.0031)
