Analyses for mitotic count (A), nuclear pleomorphism (B), and tubule formation (C) are shown in the individual panels. Each blue bar represents the agreement (quadratic-weighted kappa) between a single pathologist and the other available pathologist scores on the same cases. The yellow bar represents the agreement of the DLS-provided component score with all available pathologist’ scores on the matched set of cases. Error bars represent 95% confidence intervals computed via bootstrap. Average values in legend represent quadratic-weighted kappa or the average of all blue bars and yellow bars, respectively.
