Medical references
Thank you for contributing to Wikipedia. Remember that when adding content about health, please only use high-quality reliable sources as references. We typically use review articles, major textbooks and position statements of national or international organizations. (There are several kinds of sources that discuss health: here is how the community classifies them and uses them.) WP:MEDHOW walks you through editing step by step. A list of resources to help edit health content can be found here.

We also provide style advice about the structure and content of medicine-related encyclopedia articles. The welcome page is another good place to learn about editing the encyclopedia. If you have any questions, please feel free to drop me a note, or post to the talk page of the Wikipedia WikiProject Medicine CV9933 (talk) 11:54, 23 December 2020 (UTC)

VITAMIN E: WebMD does not meet WP:MEDRS standards, especially as for tardive dyskinesia it stated only possible effect, and offered no reference in support. For a reliable source reference on this topic, see Cochrane Database Syst Rev 2018 Jan 17;1(1):CD000209. doi: 10.1002/14651858.CD000209.pub3. Vitamin E for antipsychotic-induced tardive dyskinesia Karla Soares-Weiser, Nicola Maayan, Hanna Bergman. PMID: 29341067 PMCID: PMC6491331 for type of ref considered a reliable medical source. Authors' conclusions: "Small trials of limited quality suggest that vitamin E may protect against deterioration of TD. There is no evidence that vitamin E improves symptoms of this problematic and disfiguring condition once established. New and better trials are indicated in this under-researched area..." Based on this, the evidence is too weak to add to the Vitamin E article. David notMD (talk) 15:31, 23 December 2020 (UTC)
