Additional file 1: of Prognostic value of estrogen receptor-α and progesterone receptor in curatively resected colorectal cancer: a retrospective analysis with independent validations

Figure S1. Immunohistochemical staining for estrogen receptor-α (ER-α) and progesterone receptor (PR) in human colorectal cancer. Our data showed high expression of ER-α (A, X 100; B, X 400) and high expression of PR (C, X 100; D, X 400) low expression (E, X 100; F, X 400) in tumor tissues from patients with CRC. Table S1. Univariate survival analysis of ER-α and PR expression in training cohort. (ZIP 8731 kb)
