Fig. 1: Overview of approach and biopsied sites.
From: Pan-cancer analysis of the effect of biopsy site on tumor mutational burden observations

a Schematic representation of the approach. For each cancer type independently, patients were separated into groups according to the biopsied site of their specimen used for genomic testing. b Distribution of sample counts for each biopsied site and cancer type used for analysis. The color gradient represents the percentage of samples from a specific site within a cancer type.
