Has anyone found the study they're talking about?
This tweet is only a screenshot of the abstract.
And the trials registry entry says "No results published": https://clinicaltrials.gov/ct2/show/NCT04261517
Update: I asked the person on twitter and here it is: http://subject.med.wanfangdata.com.cn/UpLoad/Files/202003/43... Apparently it's in chinese.
