I understand what you mean, but don't think your example really fits since an increase in vitamin D in either scenario would ultimately reduce the occurrences of patients showing low vitamin D levels. And this seems to be a fairly consistent finding across multiple studies that use different controls/stratification/etc.
Or do you mean people may be becoming deficient in vitamin D as a result of Covid? If so, would be interesting to know their prior vitamin D levels.
- JshWright 6y agoI'm not entirely sure you're replying to the correct comment, but just in case... I mean the population of people who are more likely to be hospitalized due to COVID also happens to be the population of people that is more likely to be deficient in vit D, and neither of those things have to cause the other.

- rblatz 6y agoAn increase in Vitamin D levels may or may not impact COVID 19 hospitalization rates. Just like lowering ice cream sales won’t change the murder rate. Even though increased Ice cream sales is correlated with increase murder rate.
- asveikau 6y agoI know your point is that correlation does not mean causation (though maybe those are correlated?), however, that really makes it sound like guys like Ben & Jerry have blood on their hands.
- beagle3 6y agorblatz is referring to a well known correlation: more nursery happen in summer. More ice cream gets sold in summer. Therefore, ice cream sales are correlated with murders. This correlation is not random - it holds across geographic boundaries and time. But it is not causal - decreasing ice cream sales (By limiting supply, raising price, etc) will not reduce murders. Decreasing murders (By more police intervention, limiting arms sales) does not reDuce ice cream sales. Similarly, vitamin D may be The ice cream analog. COVID 19 may be the murder analog, and if that’s true, we don’t yet know what summer’s analog here - could be obesity, or genetic factors, or something else. We don’t know.
