Kaplan–Meier analysis of association between IL-6 and IL-10 expression with breast cancer prognosis. High IL-6 expression is significantly associated with improved disease-free survival (P = 0.007, a) and improved breast cancer-specific survival (P = 0.017, b). High IL-10 expression is significantly associated with improved disease-free survival (P = 0.027, c) but not breast cancer-specific survival (P = 0.150, d). Significance was determined using the log-rank test. Black represents high expression and grey represents low expression of the cytokine
