Literature screening method

Literature screening was mainly divided into three steps. First, the titles and abstracts of the research article were read, and literature that was irrelevant to this study was excluded. Then, the full text was read, data in the research results were analyzed, and any literature that did not meet the inclusion requirements was excluded. Finally, the quality evaluation was performed, and two experts independently extracted the data with a unified Excel table. It was crucial that three preliminary experiments had been performed before data extraction. If there were inconsistencies among experts, a consensus was sought through discussion, or a third expert was invited to arbitrate.
