Coverage at the target regions in cfDNA samples. a) pre-surgery cfDNA samples. b) post-surgery cfDNA samples. Mean target region coverage (black squares) and the coverage for the nucleotide positions for which somatic mutations were detected in the corresponding tumour samples is indicated. Dot colours indicate coverage at the nucleotide position for which the mutant allele was (orange dots) or was not (green dots) detected in cfDNA
