I'm posting a link to a page of information that is supposed to be an "update" on the efficacy of Hydroxychloroquine. All it doesw is rehash the old bad studies. Most of them deal with hospitalized patients although the advice of all those who advocate it is that it is to be used within the first week of symptoms and they prescribe it to outpatients. Used after the virus has become established it is not effective.
Many of the studies do not discriminate between healthy and unheqalthy, or old and young patients so that the positive results shown are probably not due to the treatment but to the fact that those who did well were younger and healthier in the first place, whereas those who didn't do well or died were probably older or had other risk factors. There is no way to tell, but what is imputed to the treatmetn is probably not due to the treatment under such conditions. It's pretty clear that if anyone died at all it would have to be because the treatment was given too late, as all those who have used it effectively have said many times. Even to go on reporting such inept studies makes this page utterly untrustworthy.
And of course those who have adovcated for the drug are not mentioned. Dr. Zelenko, Dr. Harvey Risch of Yale, Dr. Simone Gold, Dr. Daniel Wohlgelernter, Dr. Stella Emmanuel.
Some of them are silenced on the internet for "misinformation" because they advocate the drug and disagree with these studies. This is beyond ridiculous into criminal.
