Abbreviations: MyD88, myeloid differentiation primary response 88; TLR4, Toll-like receptor 4; ER, estrogen receptor; PR, progesterone receptor; HER-2, human epidermal growth factor receptor 2; HR, hazard ratio; CI, confidence interval.

P-value was calculated with a two-sided χ2 test.

Bold values denote P≤0.05.
