Categorized Pearson’s product-moment correlation of immune cell landscape of breast cancer compared with TCGA gene expression of IL-34, CSF-1, CSF-1R, PTPRZ1, and SDC1 (syndecan-1) (TIMER).

r, categorized Pearson’s correlation coefficient;

(---), −1.0 to −0.5, strong negative association; (--), −0.5 to −0.3, weak negative association; (−), −0.3 to 0.1, little association.

(+), +0.1 to 0.3, little association; (++) +0.3 to +0.5, weak positive association; (+++), +0.5 to +1.0, strong positive association.
