Fig. 4From: Inter-observer variation in two-dimensional and three-dimensional ultrasound measurement of papillary thyroid microcarcinomaBland-Altman plots of PTMC measurement by the two observers. A. Maximum diameter; B. 2DUS volume; C.3DUS volume; The x-axes showed the average of measurements by the two observers. The y-axes showed the ratio between the two observers. Solid lines were the ratio(bias). Top and bottom dashed lines correspond to upper and lower margins of 95% limits-of-agreement(LOA)Back to article page
