Principal component analysis (PCA) made for the proteome of all perioperative and postoperative samples from fundus (A), corpus (B) and antrum (C). Perioperative samples have been encircled in the Fundus/Corpus/Antrum plot (D). Percentages along the axes of the Fundus/Corpus/Antrum plot display the amount of variance that each axis represent. The plots illustrate that the perioperative proteomes are grouped more closely than the postoperative ones, who show more variability. Postoperatively, proteomes from the fundus show more variability when compared to the corpus and the antrum.
