Overview of the results of cfDNA liquid biopsy. A the quantity of extracted cfDNA grouped by tumor types. B Histogram showing the distribution of the depth of sequencing across all samples. C Allele frequency of mutant across all samples. The percentage in the plot represent the proportion of variants within each range of allele frequency. D Allele frequency of each mutant grouped by gene. CTNNB1 was wildtype in all tested samples and was not shown in the plot
