What a patronising, self-satisfied, pile of giblets this man is.
He's complaining that cardiologists find heart problems - that no virologists have participated in this study. That is because a significant cardiac effect of this drug has been noted, and it was decided to investigate whether the deleterious effects of the drug on the heart were more dangerous than Covid (ie - is the cure worse than the illness).
They haven't listed all of the authors on the paper "usually when there are 000's of subjects there are many, many authors - Here there are only four. This is suspicious". No it isn't - this sounds like a meta-analysis where the authors have taken both their own data and that of other researchers and combined the results. The other authors and their papers will be noted in the references at the end of the paper. It also enables equal cohorts of subjects with different underlying conditions to be assembled. There are 90,000 subjects in this study - that is HUGE.
I could go on. I haven't read this paper, obviously, but he is cherry-picking the information he is sharing.
This idiot is twisting the data to make himself look clever. He is effectively telling people that hydroxychloroquine won't do any harm (unless you have an underlying heart condition). There are millions of people out there who have underlying conditions that they are unaware of. He admits that he is not a cardiologist (or a research clinician). I have no idea whether the paper is reliable or not - and none of us can tell that from what he has said, because he is self-aggrandising and only giving some selected information. A good research paper asks as many questions as it answers - nothing is as straightforward as Dr "Thingy" is suggesting (can't remember his name and don't care.) The purpose is to stimulate further research and get ever closer to the truth.
I do know, however, that the Lancet usually doesn't publish rubbish studies. And that it is common for studies to be challenged and discussed and examined to determine significance, so the open letter by the "doctors and pharma companies" is not as impressive as it might otherwise be - especially when pharma companies are involved, and many of these doctors will be dependent upon them for research money.
I've been prescribed hydroxyquinochloroquine in the past (I have an auto-immune condition which affects my nervous system) and I had to come off it because it caused a serious cardiac arrhthymia. Ok - I'm just one person, but cardiac problems is a side effect and is obviously occurring often enough to be of concern.
Covid affects breathing. If you can't breathe, and your heart is fighting to beat, you really are on a hiding to nothing,
