LVM, left ventricular mass; LVMI, left ventricular mass index; BSA, body surface area; H, height; W, weight; CV, cardiovascular. HR and its CI were calculated using Cox proportional hazard regression analysis. In multivariate analysis, covariates were age, sex, current smoking, causes of chronic kidney disease, systolic blood pressure ≥ 127 mmHg, diastolic blood pressure ≥ 77 mmHg, blood urea nitrogen≥ 8.6 mmol/l, estimated glomerular filtration rate ≥ 46.3 ml/min/1.73m², bilirubin ≥ 10.3 μmol/l, albumin ≥ 42 g/l, cholesterol ≥ 4.4 mmol/l, hemoglobin ≥ 12.8 g/dl, body mass index, fasting glucose, urine protein creatinine ratio, and high sensitive C-reactive protein.

* meant results using time-dependent Cox hazard regression analysis.
