And on the attachment -link that you put says "(56 patients who did not declare any symptom before treatment start were excluded and 77 with missing data) ", does it means tha asymptomatic cases were excluded from the research?
I don't think so, since he cites 1000+ cases were with NEWS score between 0-4. A score of 0 means no symptoms.
If the treatment does not work, why are Chinese and Koreans using it?
A lot of people are using it, because they're desperate for anything. But no one has proven it works. If there is a paper from Korea about this, then I haven't seen it. I hope it works, but until someone comes out with real research, we can't determine this.
Also, the Chinese did some double-blind tests. Some small researches are published, but the majority are not yet published.
I haven't seen any data on this Chinese double blind test, other than basically an abstract, without any data whatsoever. Which is kinda suspicious in itself, since they published the initial abstract in February. Should be plenty of time to provide the supporting evidence.
And to frame it in a real situation, what would you do if you get coronavirus in Indonesia and start getting moderate symptoms?
Seeing that I don't have any counter-indication to HCQ, and I can have a doctor supervise this treatment, I may take it. Still doesn't mean it actually works though. Also as far as I know, no one is receiving either CQ or HCQ in Indonesia for CV19 right now, despite it being available.
Now on to some conjecture:
I feel that HCQ probably works on mild cases based on the proposed mechanism that it works (i.e. blocks replication the virus by allowing zinc to enter cells). It probably doesn't work on severe cases, because once your own immune system is trying to kill you, it is too late.
So the interesting area of research is either a) can you use it as a prophylactic? Prevent any viral replication at the onset?, b) can you use it on mild cases to prevent it becoming a severe case?, and c) does it in mild/moderate cases quicken the time to heal?
I believe there is research being done in all 3 situations, and we should see some real conclusions in the next month or so.
