miR-320a expression does not vary in subgroups defined by categorical variables associated with Arrhythmogenic CardioMyopathy (ACM) severity.

	MAE+	MAE−	p
n	24	12
miR-320a	0.35 ± 0.03	0.42 ± 0.05	0.22
	Severe ACM (imaging)	Mild ACM (imaging)	p
n	11	18
miR-320a	0.31 ± 0.04	0.37 ± 0.03	0.16

MAE⁺, patients presenting with a history of Major Arrhythmic Events; MAE⁻, patients not presenting history of MAE; miR-320a, relative expression levels showed as mean fold change ± SEM (calculated with respect to HC). Severe/Mild ACM (imaging), patients presenting severe or mild ventricular impairment, respectively (defined as absence of ventricular dilation and/or bulging at cardiac echocardiography or magnetic resonance imaging). For each variable the p-value of the Fisher’s exact test is reported.
