Begg’s test and Egger’s test assessed potential publication bias in studies evaluating IL-17 expression in patients with solid tumors. Begg’s test assessed potential publication bias in meta-analysis of IL-17 on (A) clinical staging, (B) OS and (C) DFS, and Egger’s test in meta-analysis of IL-17 on (D) clinical staging, (E) OS and (F) DFS. The result of Begg’s test showed no statistically significance (P = 0.564 > 0.10, P = 0.516 > 0.10 and P = 0.464 > 0.10, respectively). The Egger’s test showed no statistically significance in meta-analysis of IL-17 on clinical staging and OS (P = 0.178 > 0.05 and P = 0.730 > 0.05, respectively), but potential publication bias were found in meta-analysis of IL-17 on DFS (P = 0.006 < 0.05).
