Model targets

Cohen’s Kappa (SD)

Accuracy (SD)

Tumor grade only

0.54 (± 0.10)

0.77 (± 0.05)

Tumor grade and component grades

0.61 (± 0.09)

0.80 (± 0.05)

Tumor grade, component grades and HR and HER2 status

0.58 (± 0.09)

0.79 (± 0.05)

  1. The results for three models trained on different sets of targets are shown on the validation set (n = 142). The standard deviation (SD) was calculated using bootstrapping.
  2. HR hormone receptor.
