Comparison of original, annotated, and algorithm-predicted images in the single-finding models. (A) Portal area, connective tissue, infiltration, necrosis, fibrosis, and vacuolation in each algorithm prediction and ground-truth annotation. (B) Linear regression was used to compare the number of pixels annotated by an accredited toxicologic pathologist against those predicted by the established single-finding models for portal area, infiltration, necrosis, vacuolation, and connective tissue (including fibrosis).
