  1. Results are presented as number (percentage), mean ± standard deviation, or median (interquartile range). N, number of patients with available data; LVEF, left ventricular ejection fraction; EF, ejection fraction; LVd, left ventricular diastolic diameter; LVPW, left ventricular posterior wall thickness; IVSd, interventricular septal thickness in diastole; LVM, left ventricular mass (area-length method); LVMi, left ventricular mass index (corrected for body surface area); LAd, left atrium diameter; PAP, pulmonary artery pressure; RAP, right atrial pressure; RV, right ventricle; ARd, aortic root diameter; RWMA, regional wall motion abnormalities. Percentages exclude missing values. The three eGFR groups were statistically different (P value for trend < 0.001 for all parameters except LVd; p = 0.01 for LVd)
