ZNF423 and cholangiocarcinoma: In addition, as presented in a Kaplan–Meier plot (Figure 1C), when comparing survival between two groups of CCA patients, the group of patients having high levels of both ZNF423 and 8-oxodG had significantly (p = 0.047, log-rank test) shorter survival time compared with those patients with the other patterns (i.e., high ZNF423 alone, high 8-oxodG alone and low levels of both ZNF423 and 8-oxodG).
