Fig. 3

Correlation (ac) and Bland–Altman plot (df) for EA between CCTA and RCCT using three thresholds. Mean EA [HU] is plotted against the relative difference of both measurements. Both dotted lines represent the 95% confidence intervals. Threshold of fatty attenuation: N30 (− 190 HU, − 30 HU), N40 (− 190 HU, − 40 HU), and N40 (− 190 HU, − 45 HU)
