Values expressed as unstandardized coefficient β and 95% confidence interval (CI)
Covariates in the multivariate model included age, sex, dialysis vintage, current smoking habits, a history of diabetes, hypertension, and coronary artery disease, systolic and diastolic blood pressure, body mass index, albumin, fasting glucose, triglycerides, total cholesterol, hemoglobin, creatinine, total calcium, phosphorus, iPTH, log-transformed hs-CRP, Kt/V, ultrafiltration percentage, cardiothoracic ratio > 0.5, use of ACE inhibitors or ARBs, beta-blockers, and calcium channel blockers
