A) Distribution of unmapped reads across all samples in cohort 1. The blue bars correspond to benign tissue samples (n = 23), and the red bars correspond to malignant tissue samples (n = 83). B) Overview of HPV detection in the metatranscriptomics data from cohort 1. C) Distribution of unmapped reads across all samples in cohort 2. The blue bars correspond to benign tissue samples (n = 8), and the red bars correspond to malignant tissue samples (n = 16). D) Overview of HPV detection in the metatranscriptomics data from cohort 2
