CDYL and hepatocellular carcinoma: Wei et al. identified that circ-CDYL (chromodomain Y-like), combined with hepatoma-derived GF and hypoxia-inducible factor asparagine hydroxylase, are both independent markers for discrimination of early stages of HCC with an odds ratio of 1.09 (95% confidence interval [CI]: 1.02–1.17) and 124.58 (95% CI: 13.26–1170.56), respectively.
