Table 4. Intra-Observer and Inter-Observer Reproducibility According to Intra-Class Correlation for Strain Quantification on CMR.

	Intra-Observer ICC (95% CI)	Inter-Observer ICC (95% CI)
EccSAX	0.92 (0.80–0.97)	0.93 (0.83–0.97)
ErrSAX	0.98 (0.96–0.99)	0.92 (0.82–0.97)
EllLV	0.97 (0.92–0.99)	0.94 (0.86–0.98)
ErrLax	0.87 (0.71–0.95)	0.90 (0.76–0.96)

CI = confidence interval, CMR = cardiovascular magnetic resonance, Ecc_SAX = LV circumferential strain measured from short-axis cine views, Ell_LV = LV longitudinal strain measured from long-axis cine views, Err_Lax = LV radial strain measured from long-axis cine views, Err_SAX = LV radial strain measured from short-axis cine views, ICC = intra-class correlation coefficient, LV = left ventricle
