Figure 1. Expression difference of CHRDL1 in normal samples and tumour samples. (A) Expression of CHRDL1 in normal samples from TCGA and GTEx and tumour sample of LUAD. (B) Expression levels of CHRDL1 in paired tumour and adjacent samples of LUAD. (C) ROC analysis of CHRDL1 expression showing promising discrimination power between tumor and non-tumor tissues in LUAD. (D) Expression levels of CHRDL1 in Pan-cancer. ns, P{greater than or equal to}0.05; *, P<0.05; **, P<0.01; ***, P<0.001.
