Well I poked around, I’m not sure exactly what you’re seeing. One would expect more covid deaths in the placebo, and that is the case. Most of the deaths in both groups are indeed unrelated to Covid at all. You can see exact cause of death for all participants here: https://www.medrxiv.org/content/medrxiv/early/2021/07/28/202...

I suspect the number your focusing on is the 4 cardiac arrest deaths. At a glance it seems 4x higher than the one reported placebo death. But the number is 4 vs 1 for over 20k people. Why not instead focus on placebo group having 2 vs 0 myocardial infarction? The reason why not is that dying is noisy business, and things like cardiac arrest have a pretty high baseline, and this is such a small sample the variance is likely noise.

Perhaps you could present a proper statistical analysis to convince otherwise? Something similar to the methodology for determining Covid vaccine’s effectiveness in preventing Covid deaths. After all, the data is all there. I didn’t see anything resembling such an analysis in your linked source. Just the confused ramblings of someone nontechnical, clearly out of their depth in reading a fairly basic research paper.
