In the first multivariate analysis, P wave dispersion was negatively associated with the eGFR slope after adjustment for age and sex (unstandardized coefficient β = –0.020, P = 0.015) and, further adjustment for smoking, DM, hypertension, coronary artery disease, cerebrovascular disease, LVH, systolic and diastolic blood pressure, BMI, albumin, fasting glucose, log triglycerides, total cholesterol, hemoglobin, baseline eGFR, calcium-phosphorus product, uric acid, and proteinuria (unstandardized coefficient β = –0.016, P = 0.037). This evidence concerns the gene ALB and Hypertension.
