First of all, we screened the literature according to the literature abstract, excluding the articles that obviously do not meet the inclusive criteria, and then read the full article for re-screening. If any disagreement on the choice of the literature exists, a third evaluator will join to make the decision. All included literature were evaluated using The statistical software Stata version 12.0 was used to carry out the single arm Meta-analysis. Original data included in the literature were first transformed by double arcsine method to make them conform to normal distribution and then analyzed in Stata. The initial conclusion obtained by Meta-analysis was then restored using formula (P=(sin(tp/2)) 2 ) to reach final conclusion. In order to objectively evaluate the publication bias of the included literature, the Egger test with P < 0.05 as the existence of publication bias was performed, the values larger than which were considered as no publication bias.
