Accuracy is shown with respect to the average bone age rating of two raters (columns 3 and 4) and a single rater (columns 5 and 6), plus the inter-rater errors (columns 7 and 8), lower MAD and RMSE errors mean higher accuracy. n refers to the number of individual radiographs per disorder. The RMSE is stated with the 95% confidence interval. ACh achondroplasia, GDBD German Dysplastic Bone Dataset, HyCh hypochondroplasia, IUGR intrauterine growth restriction, MAD mean absolute difference, PsHPT pseudohypoparathyroidism, RMSE root mean squared error, w.r.t with respect to
