Forest plots indicated that the expression of CHD5 was significantly correlated with PFI in PRAD (p < 0.001), COAD (p = 0.02), COADREAD (p = 0.02), HNSC (p < 0.01), PCPG (p < 0.01), Glioma (p = 0.02), LGG (p = 0.03), and PAAD (p < 0.04) (Figure A3A). This evidence concerns the gene CHD5 and central nervous system cancer.
