†

Multivariable model (1): adjusts for age, sex, and the following clinical covariates: systolic BP, smoking, diabetes, total cholesterol:HDL ratio, triglycerides, and BMI.

Multivariable model (2): model (1)+LV hypertrophy+low LV ejection fraction.

LA diameter/height indicates left atrial diameter indexed to height.
