V3 diameters measured by TCS and CT according to Bland–Altman diagram. Bland–Altman plots show the agreement between TCS and CT for V3 diameter measurements for each side of measurement. Bars lines represent 95% limits of agreement, and blue lines represent the mean difference. Mean difference between CT and TCS was 0.36 mm (standard deviation (SD) 1.52 mm, 95% limits of agreement (95% LOA) − 2.7 mm to 3.3 mm) for the right side, and 0.25 mm (SD 1.47 mm, 95% LOA − 2.7 mm to 3.1 mm) for the left side
