Fig. 5From: Gene alternation of cerebrospinal fluid in patients with leptomeningeal metastases of lung adenocarcinoma using next-generation sequencingThe amounts of variant genes and MAFs in matched CSF-PLA samples. A Difference in the amounts of variant genes detected in CSF and matched PLA. B MAF in CSF cfDNA and matched samples were analysed by Fisher’s exact test. P < 0.05 was deemed statistically significant. MAF: mutant allele frequency. CSF: cerebrospinal fluid. PLA plasmaBack to article page
