  1. Proportions of PDAC and duct specimens are split into low and high groups of IHC scores. The results of Fisher's exact test are highlighted for significant differences (p ≤ 0.05) and trends (p = 0.06). Listed are percentages of specimens with high protein levels based on a total of 26 PDAC (T specimens) and 25 normal ducts (D and Dt specimens).
