Limitation
Only 11 studies were included in this meta-analysis after a comprehensive search in the main databases, indicating that the number of original research in relevant fields is still limited. No consensus has been reached for quality assessment of in vitro studies. The modified version of MINORS scale has not been validated in terms of index content as well as scoring, and the results of assessment can only be referenced conservatively. Moreover, since the findings of this review are mainly based on in vitro studies, caution must be exercised when applying the results into clinical practice.
