The database was captured in the IBM SPSS statistical package (v. 22; IBM Corporation, Armonk, NY, USA). The results obtained for the three markers (Ob-R, ER, and PR) in the six histological types were processed for association in two ways: for qualitative information (histopathological score), Fisher’s exact test was applied; for quantitative information (digital scoring), the Kruskal-Wallis and the Student-Newman-Keuls (SNK) tests were performed. To determine the relationship between Ob-R and ER and PR, Spearman’s correlation coefficient was applied. A p-value < 0.05 was considered significant.
