TABLE 7.
Immunotherapy mPFS or mOS and response probability based on different tumor mutation burden (TMB) thresholds with measurement errors for non-small-cell lung cancer (NSCLC), nasopharyngeal carcinoma (NPC), bladder, renal cell carcinoma (RCC), and melanoma. p values are reported by log-rank test and the two-sided Mann–Whitney U test.
