Evidence context
Evidence roles describe what this source helps establish inside each Investigation. They are local to that use, not permanent labels attached to the publication itself.
Investigation
A 2025 peer-reviewed independent computational reanalysis of 5,734 TCGA whole-genome samples reported far fewer reliable microbes and identified contamination/misclassification; 4,271 reprocessed samples overlap the 2022 Cell paper's TCGA subset rather than forming an independent negative patient cohort.
