Fig. 3From: Association between modified simple protein-energy wasting (PEW) score and all-cause mortality in patients receiving maintenance hemodialysisNon-adjusted Kaplan-Meier curves in the three groups divided by the mPEW-S (n = 144). A log-rank test was used to compare survival curves among groups. A two-tailed P < 0.05 was considered statistically significant. mPEW-S modified simple protein-energy wasting score. G1, patients whose mPEW-S was 0 or 1; G2, patients whose mPEW-S was 2; G3, patients whose mPEW-S was 3 or 4Back to article page
