Associations between inflammatory biomarkers and breast cancer, by estrogen receptor status and in triple-negative tumors. Odds ratios are per standard deviation increase in residuals of log-transformed biomarker concentration regressed on analytical batch, estimated from conditional logistic regression models adjusted for BMI. P-homogeneity ER compares estrogen receptor negative and positive tumors. P-homogeneity TN compares triple-negative and non-triple-negative tumors. Abbreviations: BMI body mass index, CI confidence interval, ER + estrogen receptor positive, ER- estrogen receptor negative, IFN interferon, IL interleukin, OR odds ratio, SD standard deviation, TN triple negative, TNF tumor necrosis factor
