So they controlled with 2 other groups, those diagnosed with the flu and those with respiratory trace infections. Some things stick out: 1) That we are all locked up in a state of anxiety is a little bit hard to control for especially because those factors alone may not trigger things, but those factors + COVID may actually amplify. 2) The big loophole that's nary impossible to nail down is the psychological impact of being told you have something that 'might kill you and has killed 550 000 Americans and the cause of a pandemic' vs. 'You have the normal flu go hoe you'll be fine in two days'. I once had an ailment that was actually something not so severe (lack of sleep, too much redbull and stress) and was fine a few months after adjusting, by my symptoms were so varied and odd I was sure I had the 'start of something worse'. The fact the doctors could not nail it down with a straight diagnosis sent me into kind of a panic. The 'real control group' would be people that 'Had actual COVID' but were actually told that 'They just have the regular flu' - which would be obviously next to impossible. Because the symptoms identified are common and indirect things like 'Depression and Anxiety' - it speaks even more to the mental aspects of the side effects. If for example COVID patients had '50% higher likelihood of Iron deficiency' or something like that, well, it would be easier to absorb as a straight up side effect. It might be possible to do the same kind of survey in other countries to see if the same thing holds up. It'd be interesting to see if they can normalize for things like neuroticism, and general attitudes towards the virus, deaths in the family due to COVID etc. to see if depression is more common in those who naturally tend to worry, or have more of a reason to be afraid.
