We are pleased to consider all kinds of articles, including reports of original research, for this issue.<p>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 While we welcome light-hearted fare and satire, we do not publish spoofs, hoaxes, or fabricated studies.”</i><p>See <a href="https://www.bmj.com/content/355/bmj.i6679" rel="nofollow">https://www.bmj.com/content/355/bmj.i6679</a> for examples.
