Correlation and Bland-Altman plots of vessel-based and lesion-based PCAT CT attenuation as clarified by invasive FFR. Pearson correlation analyses show the correlation vessel-based and lesion-based PCAT CT attenuation in all vessels (A), vessels with FFR > 0.80 (B) and vessels with FFR ≤ 0.80 (C), respectively. Bland-Altman plots show PCAT CT attenuation between vessel-based and lesion-based in all vessels (D), vessels with FFR >0.80 (E) and vessels with FFR ≤ 0.80 (F). The red dotted lines represent the mean difference (bias), and the blue dotted lines represent the 95% limits of agreement. FFR, fractional flow reserve; PCAT, pericoronary adipose tissue.
