When we evaluated the association between the proteins expression and the tumor lesion (breast cancerous vs. non-cancerous) in logistic regression model adjusting for age, the following five proteins resulted statistically significant according to the Bonferroni p-value: STAT5 (p < 0.0001), BMP6 (p = 0.0051), CD74 (p = 0.0034), INHA (p = 0.0085), and STAT3 (p = 0.0085). Here, INHA is linked to neoplasm.
