Their control group was people that had influenza and other respiratory conditions in the same timeframe. The hazard ratios for COVID survivors (over influenza or others) were in the 1-2% range. Meh.
- kazinator 6y agoThat's not a credible control, because influenza and respiratory conditions are not a plausible placebo for Covid-19. The subjects knew that they are not having Covid-19, which makes them different from subjects which got Covid-19 and knew it.
- Barrin92 6y agoI'm not really sure what you're trying to say, that if you control for covid-19, the effect of covid-19 goes away? Duh What you want to control for is the lockdown effects or general disease stress, not covid-19 itself. That's what you're trying to measure.
- necovek 6y agoI think the GP has a point: ideally, you'd have unaware Covid19 patients as a control group, to see if this is psychological or physiological. Those aware they had Covid19 will fear all the known-unknowns around Covid19. Those who don't think they had it wouldn't have stressed about it at all.
- c6401 5y agoWow people do incredible mental hymnastics to prove themselves they are safe and all these studies are flawed. No matter how much effort have been put into research it will never be good enough.
