Fig. 2. Bland-Altman plots of LA measured by SATM versus LATM and IVUS in the smaller lumen group.

A. Bland-Altman plot for LATM and SATM (mean difference = 1.07 mm²; 95% CI of mean difference, 0.89 to 1.25 mm²). B. Bland-Altman plot for SATM and IVUS (mean difference = 1.53 mm²; 95% CI of mean difference, 1.27 to 1.79 mm²). C. Bland-Altman plot for LATM and IVUS (mean difference = 0.46 mm²; 95% CI of mean difference, 0.27 to 0.65 mm²). LA = lumen area, S = smaller group
