It is not usually necessary to search both PubMed and Ovid Medline, even for a full systematic review. In the past, PubMed included some additional content that was not available in other versions of Medline, but Ovid Medline now includes that additional content.

Not all versions of Medline do include that additional content so, for example, you can search Medline via the Web of Science platform at UCL. We would not usually recommend this because the content of this version of Medline is slightly different to PubMed and you can't use Medline subject headings (MeSH) effectively in the Web of Science.
