Correlation of CAS-Weighted JAMRIS-SIJ Vignette Ranking with Graded or Image Ranking. Spearman’s rank correlation coefficients are plotted for each expert rater (radiologist and rheumatologist, n = 17) comparing their two methods of producing of vignette ranks, i.e., correlating the experts’ grade-only or graded image-based full profile ranking with the ranking produced by applying the experts’ own CAS-derived weights applied to consensus grades. Horizontal lines represent the median Spearman correlation for each subgroup of participants (X—grade-only vignette ranking, n = 17, O—grade + image vignette ranking, n = 12). The JAMRIS-SIJ MR image + grade vignettes.
