Table 2.

We categorize WSIs into groups with different segmentation quality levels.

WSI groups Percentage of patches with bad segmentations #. slides
Best 0% 2,346
Good 0.01–6.67% 1,246
Adequate 6.68–13.3% 593
Problematic 13.4–20.0% 302
Unacceptable >20.0% 573
or failed WSI QC

Slides identified as having unacceptable segmentation results are excluded from analysis in the rest of this work.
