Figure 4. Correlation between ZSCAN20 promoter methylation level and prognostic value of DNA methylation in HCC. (A) normal vs primary tumor, (B) gender, (C) age, (D) cancer stage, (E) tumor grade, (F) lymph node metastasis status; *P < 0.05; **P < 0.01;***P < 0.001. High methylation level of cg02487499 (G), cg14041778 (H), cg18028289 (I), cg18085998 (J), cg19855402 (K) and cg26805255 (L) correlated with worse OS.
