How did you gather the information you considered in your
review?
We performed a systematic search in
PubMed, Science Direct, EMBASE and Cochran
Library. One or a combination terms
was used in the search. The publication time of the literature was
restricted from January 1, 2000 to August 2, 2020. Two investigators
searched and screened the articles independently. In case of
disagreement about the literature search, a third reviewer would engage
in the discussion until a consensus was reached.
