Out of the 80 ROIs, Aiforia over-estimated the score in 59% (47/80; in some ROIs the image analysis tool counted the Ki67 positive non-tumor cells, or faintly stained tumor cells as Ki67 positive tumor cells), under-estimated in 21% (17/80; in some ROIs the image analysis tool counted more cells by including several non-tumor cells, while counting the same number of positive tumor cells), and provided concordant results in 20% (16/80; all 16 ROIs had no Ki67 positive cells). Here, MKI67 is linked to neoplasm.
