Search Strategy
Electronic databases such as MEDLINE (Ovid Interface), EMBASE (Ovid
Interface), and SCOPUS were searched to obtain peer-reviewed studies
indexed from database conception to October 21, 2022. Additional
relevant studies published on Monkeypox with data on Gastrointestinal
and/or Liver Manifestations were searched through hand-searching in the
New England Journal of Medicine (NEJM), the Lancet series, JAMA, BMJ,
Gastroenterology, Gut, American Journal of Gastroenterology, and the US
Centers for Disease Control and Prevention. Additionally, reference
lists of included studies were screened for potentially eligible
studies. Only articles published in English were included in this
systematic review. The entire search strategy was created with the help
of a librarian, including keywords such as “Monkeypox,”
“Gastrointestinal,” and “Liver,” and was adjusted based on the
specific electronic databases (Table S2 ).
