Have a link? I missed those studied.
Results aren't really as described here. Some patients recover, but about 1/3 had persistent lung findings and many had decreased lung function (as measured by DLCO).

Also note for anyone reading the above study: they were hospitalized patients, with critical excluded. That would be “moderate” in the technical terms used to describe the virus.
