Correction for position by redefining the first position in each ROI as the most anterior coronal slice included in both ROIs. Inter-rater (blue) and intra-rater variability (red) for all methods and position. The repeatability coefficient (intra-rater) was expressed as an interval with the same midpoint as the corresponding limit of agreement (inter-rater) for easier comparisons
