I have decided to end my project of maintaining a spreadsheet of #COVID19 studies. After thousands of hours of effort, I think the time has come to move on. The flow of studies has been slowing over the past year.

This spreadsheet will remain online for those interested. And, you can check for newer studies on http://scholar.google.com.

I will continue to track COVID levels and risks in the US.
