Model was adjusted for age, sex, region, smoking (never, former, current), body mass index (continuous), dyslipidemia (no/yes), fasting glucose level (continuous), estimated glomerular filtration rate (continuous), systolic BP (continuous), and BP treatment (no/yes). BP indicates blood pressure; CI, confidence interval; E/A, early peak rapid filling velocity to peak atrial filling velocity; LV, left ventricular; and MD, mean difference.
