A (non-systematic) evidence review of 2020

As 2021 hoves into view, we look back at a year of extraordinary evidence. Helen Macdonald is joined by Joe Ross, one of The BMJ's research editors, as well as a researcher at Yale. They discuss the way in which clinical pre-prints have become an important part of the research ecosystem, especially during the pandemic, and pick up on some of the non-coronavirus things you might have missed in the deluge of data.
