Bar graph of relative expression levels of CDH1, TWIST1, SNAIL and SLUG. Expression levels of CDH1 mRNA (a) and TWIST1 mRNA (b) are shown for controls (n = 45 and 47 for CDH1 and TWIST1, respectively) and eutopic (n = 42) and ectopic endometrial samples (n = 62). Expression levels of SNAIL mRNA (c) and SLUG mRNA (d) are shown for controls (n = 47) and eutopic (n = 42) and ectopic endometrial samples (n = 62). Expression levels were normalized to ß-actin and GAPDH. All p-values were analyzed by Mann–Whitney U Tests
