Computer assistance also improved the association between GATA6 IHC expression and tumor size change in patients receiving first-line mFFX (P = 0.015 vs. P = 0.20 for pathologist 1; P = 0.015 vs. P = 0.19 for pathologist 2, with and without computer assistance respectively; Fig. 4). Here, GATA6 is linked to neoplasm.
