Mean absolute deviation of observers’ T-score-DG from the reference T-score-DG was 0.95 +/-096 at attempt A and has improved to 0.63 +/-0.89 at attempt B, but the difference was not statistically significant (p=0.056). Respective mean deviations for T-score-BT were 0.9 +/-1.09 and 0.71 +/-0.97 (p=0.228), respectively. Individual Case- and observer-specific deviations from the reference are presented in Figure 1. Figure 2 summarizes the kappa statistics for comparisons between observers’ and reference rating of individual anatomical subsites and T-score at attempts A and B.
