  1. HD hemodialysis, DM diabetes mellitus, BMI body mass index. Coefficients printed in boldface indicate P < 0.05. For aGA-M, the coefficients were calculated for diabetic subjects only. Correlations between continuous variables were assessed by Pearson or Spearman correlation coefficients according to the distribution of the variables. For combinations involving dichotomous variables (gender and diabetes status), point biserial correlation coefficients are shown and the P-values are determined by Welch t-test. ***P < 0.001, **P < 0.01, *P < 0.05.
