a
P value for global difference; significance testing was by t-test or Wilcoxon rank-sum test for continuous variables and Chi2 test for dichotomous variables.
Parameters are presented as mean ±standard deviation or median (inter-quartile range).
DM, diabetes mellitus; CHF, congestive heart failure; AVF, arteriovenous fistula; AVG, arteriovenous graft; SBP, systolic blood pressure; DBP, diastolic blood pressure; ESKD, End-stage kidney disease (vs reference of acute kidney injury requiring hemodialysis); UF, ultrafiltration at first session.
