Figure 4.

Grading cross tabulation. Green shading indicates concordant grading between pathologists. Red shading indicates that low-volume prostate cancer was missed by 1 of the pathologists. In panels A and B, pink and yellow shading indicate cases that were overgraded and undergraded, respectively, by pathologists 2 and 3 vs pathologist 1. In panel C, pink and yellow shading indicate cases that were overgraded and undergraded, respectively, by pathologist 3 vs pathologist 2. Pathologist 1 was W.H., pathologist 2 was K.A.I., and pathologist 3 was R.H. AI indicates artificial intelligence; BPT, benign prostatic tumor; and GGG, Gleason grade group.
