Limitations
The limitations of this study are as follows. First, we included only English literature. Ignore articles published in other languages. Second, we did not search for grey literature and unpublished studies. Additionally, articles did not provide specific values, but presented the research results in the form of charts or words, which affected the results of meta-analysis. It is worth mentioning that despite the rapid development of information technology, the research in this paper is all from developed countries. Finally, these variations might contribute to bias. Due to the limited number of articles, we did not use funnel plots for publication bias, so we are not sure about publication bias. However, given that some studies have reported negative results, we have reason to believe that the possibility of release bias is low.
