Cox proportional hazards regression with death as a competing risk showing the association of LV systolic function, diastolic function and LA volume with incident AF.

	Univariate^*		Multivariate^†
	HR (95% CI)	P value	HR (95% CI)	P value
GLS, per 1% decrease	1.20 (1.08-1.34)	0.001	1.22 (1.04-1.43)	0.015
LVEF, per 1% decrease	1.00 (0.92-1.08)	0.923	0.96 (0.90-1.02)	0.176
LAVi, per ml/m² increase	1.11 (1.07-1.16)	<0.001	1.12 (1.07-1.17)	<0.001
LV diastolic dysfunction	2.93 (1.27-6.74)	0.012	1.19 (0.46-3.07)	0.715

Each variable is entered in a separate model.

^†

All variables are included in the same model. Covariates: age, obesity, hypertension, anti-hypertensive treatment, coronary artery disease, LV mass index, relative wall thickness.

HR: Hazard ratio. CI: Confidence interval. LV: Left ventricular. GLS: Global longitudinal strain. LVEF: LV ejection fraction. LAVi: Left atrial volume index.
