LAV max, LA maximum volume; LAV pre-A, LA pre-A volume; LAV min, LA minimum volume; AVG, atrioventricular groove; IAS, interatrial septum.

Model 1: Univariate.

Model 2: Multivariate: adjusted for age, gender.

Model 3: Multivariate: adjusted for age, gender, eGFR, LV mass, history of hypertension, diabetes, hyperlipidemia or CAD.
