Multivariable analysis for the development of atrial fibrillation

			Model 1		Model 2		Model 3
Variable	Unadjusted OR (CI 95%)	P	Adjusted OR (CI 95%)	P	Adjusted OR (CI 95%)	P	Adjusted OR (CI 95%)	P
Micro-AF	5.3 (2.3–12.5)	< 0.001	4.7 (2.0–11.1)	< 0.001	5.1 (2.1–12.8)	< 0.001	4.6 (1.8–11.5)	< 0.001

Model 1: Adjusted for height and analysed signal time

Model 2: Adjusted for age, hypertension, heart failure and stroke

Model 3: Adjusted for height, analysed signal time, age, hypertension, heart failure and stroke

AF atrial fibrillation, CI confidence interval, Micro-AF short episodes of irregular supraventricular tachycardia, always refers to when it is seen during intermittent ECG recordings; OR odds ratio, SVEBs supraventricular ectopic beats
