From: The characteristics of ctDNA reveal the high complexity in matching the corresponding tumor tissues
ctDNA had high concordance to corresponding tumor tissues from late-stage lung cancer patients. a The summary of mutations in the standard group of patients. b The Pearson correlation of allele frequencies (AFs) between ctDNA and tumor tissues. c The curve of ctDNA sensitivity to detect tumor-matched SNVs and Indels at different cutoffs of tumor allelic frequency. d The receiver operating characteristic (ROC) curve to detect tumor-matched SNVs and Indels from ctDNA. e The sensitivity of ctDNA in detecting EGFR hotspot mutations. f The correlation of AFs between ctDNA and ddPCR
