a
Model 1 adjusted for age, sex, diabetes, hypertension, coronary artery disease and Charlson Comorbidity Index.
b
Model 2 adjusted for covariates in Model 1 and additionally adjusted for hemodialysis vintage, UF/DW, pre-HD SBP, blood flow, dialysate flow, dialysate average temperature, conductivity and dialysate calcium.
c
Model 3 further adjusted for antihypertensive medications and iron infusion, but omitted covariate of hypertension to avoid collinearity.
