Fig 3. Forest and funnel plots of CDH13, RUNX3 and APC.
The forest plots of CDH13, RUNX3 and APC displayed the effect size and 95% CIs for the included studies. Our results showed that the total ORs of CDH13, RUNX3 and APC demonstrated that the methylation of CDH13, RUNX3 and APC in AC were significantly more frequent than in SCC. Funnel plots of meta-analyses of CDH13, RUNX3 and APC demonstrated no publication biases in the included studies. The details of abbreviations (M-H, ORs, CIs, and SE) and weight were shown in the legends of Fig 2.
