Reader study results evaluating completeness, correctness and conciseness (columns) across individual readers and pooled across readers. Scores are on the range [−10, 10], where positive scores denote that the best model is preferred to the medical expert. Asterisks (*) on pooled rows denote statistical significance by a one-sided Wilcoxon signed-rank test, P < 0.001. Intra-class correlation (ICC) values across readers are on a range of [−1, 1] where −1, 0 and +1 correspond to negative, no and positive correlations, respectively.
