  1. Note: A p-value threshold of 0.01 was used for all gene expression algorithms. True positive rate (TPR) is the proportion of high-level microsatellite instability (MSI-H) cases detected by each algorithm. False positive rate (FPR) is the proportion of non-hypermutated cases falsely called hypermutated by the gene expression algorithms. Numbers in parentheses give 95% confidence intervals calculated by the Wilson method. COAD colon adenocarcinoma, STAD stomach adenocarcinoma, UCEC uterine corpus endometrial carcinoma
