Yes, an English medical case report can be considered SCI if it meets the criteria set by the indexing system. SCI is a database that indexes peer-reviewed literature in various scientific fields, including medicine. To be included in SCI, a case report should meet certain quality standards, such as originality, significance, and thoroughness. Additionally, the report should be published in a reputable journal that is indexed in SCI. If a case report meets these criteria, it can be cited and have an impact factor, which are important measures of academic influence.
