Pathological and molecular estimates of tumor-infiltrating lymphocytes in Black and White breast cancer patients in the Women’s Circle of Health Study. A) Boxplots of pathological tumor-infiltrating lymphocytes (TIL) scores by race, with and without stratification by tumor hormone receptor (HR) status. The bar in the middle of a box indicates the subgroup median, and the lower and upper edges indicate the first and third quartiles, respectively. The extended lines indicate the range in each subgroup. P values were derived from 2-sided Wilcoxon test between Black and White patients. B) Boxplots of molecular TIL scores estimated based on immune panel gene expression data, with and without stratification by tumor hormone receptor status.
