MCL1 and atrial fibrillation: Two clinical features (including gender and BMI) and three-volume values (including LA volume, EAT volume, and LA-EAT volume) among all the clinical characteristics and volume values were selected by univariate analysis (Table 2), the Cmodel was then built based on two independent predictors (gender and BMI) of the AF subtype, and the Vmodel was built based on three independent predictors (LA, EAT, and LA-EAT volumes) of the AF subtype.
