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 ).
