	LARS			LACS		LABS
Predictors	Mean differences	p-value		Mean differences	p-value	Mean differences	p-value
Age				-13,79	0,001
Sex	-1,54	0,034
GLS, %	1,13	0,0005		0,64	0,0005
LAEF, %	0,44	0,0005		0,28	0,0005

A = peak mitral inflow late velocity; E = peak mitral inflow early velocity; e’ mean = mitral annular early velocity; GLS = global longitudinal strain; LABS = left atrial booster strain; LACS = left atrial conduction strain; LAEF = left atrial ejection fraction; LARS = left atrial reservoir strain; LASI = left atrial stiffness index
