Reproducibility of native T₁ measurement in AF patients and healthy controls

	10 healthy controls		10 AF subjects
	Intra-observer reproducibility	Inter-observer reproducibility	Intra-observer reproducibility	Inter-observer reproducibility
Repeatability coefficient	25msec	27msec	40msec	46msec
Intra class correlation coefficient	0.96 (95%CI: 0.85–0.99, p<0.05)	0.95 (95%CI: 0.80–0.99, p<0.05)	0.92 (95%CI: 0.87–0.95, p<0.05)	0.91 (95%CI: 0.86–0.94, p<0.05)
Coefficient of Variation	0.8%	1.1%	1.4%	1.6%

AF, atrial fibrillation; CI, confidence interval

Repeatability coefficients were calculated as 1.96 times the standard deviation of the differences on the Bland-Altman plots.
