Literature review
We did not limit the publication years and conducted a full-text literature search in the PubMed, Science ISI Web,Embase and Wanfang, Chinese National Knowledge Infrastructure (CNKI), and Weipu and databases. Search to identify all studies that may involve the following keywords: “Epstein-Barr virus infection” or “chronic Epstein-Barr virus infectious diseases” and “enteritis” or “gastrointestinal symptoms”. We retrieved documents and perused the reference lists that were eligible retroactively to avoid missing relevant literature.
A total of 13 English studies and 5 Chinese studies were retrieved. After a careful review of the full text, 7 studies[7-13] (3 Chinese and 4 English) and 26 case reports of CAEBV were included in the statistical analysis.
