The shapes of the funnel plots (Figure 6) seemed symmetrical, and Begg’s test suggested that there was no publication bias [27] for studies of XPF-rs2276466 associations with cancer risk in the current meta-analysis (recessive model: P=0.350; dominant model: P=0.213; additive model: P=0.119, no value, respectively). This evidence concerns the gene ERCC4 and cancer.
