Table II.
Measurement of the consistency between regions of registration and intra- and inter-observers reproducibility. Bland-Altman means (in mm), standard deviation and 95% limits of agreement (LoA, in mm) for comparison between corresponding x, y, z coordinates from corresponding landmarks (1 to 6).
