For the first two authors the Cohen’s kappa linear weighted coefficient shows intra- and inter- observed values ranging from 0.34 to 0.69 (Table 4), all significant at p < 10−3 . In a single case the two evaluators have a low inter-observer score (for the orbital margin, Cohen’s kappa with linear weighting 0.34). The performance improved in this case (kappa = 0.52) after using the additional criteria of sco- ring. However, intra-observer concordance correlation coefficients of reproducibility—CCC (Lin, 1989) were low; thus, the first and second author obtained intra-observer scores of 0.65 and 0.78 for orbital,
