Note: ^aUnadjusted model.

^bAdjusted model for age, sex, history of DM, CVDs.

^cAdjusted model for model 1 + dialysis vintage, dialysis type, number of AHAs, LDL-C, and serum albumin.

Abbreviations: HR, hazard ratio; CI, confidence interval; SBP, systolic blood pressure; AHA, antihypertensive agents; LDL-C, low-density lipoprotein cholesterol.
