These examples use NICE Evidence Search - HDAS. For single journal articles, you have the option to check the journal website or search for an article on PubMed, Medline or EMBASE to check its status.
When searching, the best search strategy is to combine the search for your topic with the appropriate thesaural terms for retraction. These terms are explained below. This requires you to search in specific fields. See the NICE Evidence Search Guide YouTube video on In field searching. This may be blocked on some NHS Networks.
