From: Concordance of HER2-low scoring in breast carcinomas among pathologists
The heatmap displays Cohen’s weighted kappa values among pathologist for two different sets of cases: the whole cohort (upper triangle) and the HER2-low cases (lower triangle). The x-axis and y-axis represent the indices of the pathologist (P1 to P61), and the colour scale indicates the kappa values, ranging from 0 (no agreement) to 1 (perfect agreement). C-All indicates the consensus scores for all cases, and C-Low indicates the consensus score (reference scores) only for the HER2-low cases.
