COVID-19 trial protocols

Research into COVID-19 is exploding, as it needs to, and this includes randomised trials.  Between 23rd of January and 8th March 2020 there were 382 registered COVID-19 trials. Almost all of those were in China but the virus is now global and trials will move with it.

Researchers need to know about these trials, and they need to know quickly.  

Trials are therefore implementing a new, simplified process for handling COVID-19 trial protocols which is must faster and much simpler for authors. Please visit trialsjournal.biomedcentral.com/covid-19 for more information.
