Surgery in England during COVID-19, and the trial that cites it
Did national analyses of surgery during the pandemic feed into later clinical research?
Read this first: A trial registration citing these papers shows they were part of its background. It does not show the trial was designed because of them, or that either changed surgical practice.

What remains unknown

- Guideline or policy use: no source for surgical guidance or NHS recovery planning citations is imported yet.
- The trial's own results: not yet published or not yet listed on its registration.
