Fig. 3: Comparing stromal tumor-infiltrating lymphocytes.

Violin plots showing the percentage of stromal TILs in the tumor area for the full H&E-stained section. Percentage is scored comparing breast cancers in the lowest and highest quintiles of MD within a the entire breast cancer cohort, b luminal cancers only, c and combined luminal subtype and ductal histology cancers. Assessing breast cancers in the lowest quintile of MD only, the percentage of stromal TILS was scored comparing TP53 wild type and TP53 mutant breast cancers within d the entire breast cancer cohort, e luminal cancers only, f and combined luminal subtype and ductal histology cancers. Mann–Whitney test was applied.
