This is an article from the BMJ Christmas issue. https://www.bmj.com/about-bmj/resources-authors/article-types/christmas-issue https://www.bmj.com/about-bmj/resources-authors/article-type...: “We publish a special two-week issue of The BMJ over Christmas and New Year. We are pleased to consider all kinds of articles, including reports of original research, for this issue. The soul of the Christmas issue is originality. We don’t want to publish anything that resembles anything we’ve published before. While we welcome light-hearted fare and satire, we do not publish spoofs, hoaxes, or fabricated studies.” See https://www.bmj.com/content/355/bmj.i6679 https://www.bmj.com/content/355/bmj.i6679 for examples.
