MDCT-derived LA volume, wall thickness and segmented wall volume, stratified by study sub-groups

	Total (N = 80)	Paroxysmal AF (N = 30)	Persistent AF (N = 30)	Controls (N = 20)	P-valuea
LA volume (mL)	100 ± 20	106 ± 21	102 ± 14	89 ± 22	0.007
LA wall thickness (mm)	1.25 ± 0.22	1.25 ± 0.22	1.33 ± 0.20	1.13 ± 0.21	0.006
LA segmented wall volume (mL)	11.1 ± 4.1	11.3 ± 4.6	11.9 ± 4.3	9.7 ± 2.7	0.181

^aReported P-value refers to one-way ANOVA test between the three sub-group of interest; P-values < 0.05 are reported in bold.

AF, atrial fibrillation; LA, left atrial.
