Supplementary Figure S4 from Molecular Characterization of NUT Carcinoma: A Report from the NUT Carcinoma Registry

Supplementary Figure S4: Tumor mutation burden and PD-L1 expression among cases with DNA NGS testing. (A) Box-and-whisker plot showing tumor mutation burden (B) Bar chart showing the distribution of PD-L1 expression levels, stratified by tumor proportion score and combined proportion score. Expression levels are grouped into <1%, 1–49%, and ≥50%.
