(A) Boxplot of adjusted mutation rate residuals (tumor mutational burden, TMB) by sex for early-onset and late-onset non-hypermutated CRC. The residual of adjusted mutation rates and P-values were derived from models adjusted for race and ethnicity, tumor site and histology, sequencing assay, and sample type.
(B-C) Mutation frequencies between genes differentially expressed between early-onset vs late-onset non-hypermutated CRC cases that reached statistical significance (P<0.05) for (B) females and (C) males. </p/>(D) Inverse mutation frequencies for EP300 in non-hypermutated CRCs among young patients by sex.
