Also worth noting that Europe in general is really far north compared to the US. Spain is on the same latitude more or less as NYC.

That's misleading because Europe is on the western edge of the Eurasian landmass, meaning it gets the benefit of warm air heated up over the ocean. By the time the air gets to the eastern edge of a landmass it's a lot colder, which is why London has a milder average temperature than NY and Vladivostok, despite being almost 10° further north than both.

Yes, but vitamin D production relates to direct sunlight ... I think the angle of the sun and amount of atmosphere it has to go through affects UV amounts so a warmer European country does have less direct sun therefor more potential for vitamin D deficiency ...

TBH I am not super solid on every one of these details.

That's a good point, but this paper seems to indicate that the amount of sunlight required over the summer in order to build enough vitamin D to last over winter isn't much for white Caucasians in the UK - nine minutes each day at lunchtime between March and September, assuming shorts and t-shirts are worn during the summer:

Yes that's true, but the 17M figure isn't the interesting / groundbreaking thing. At least it shouldn't be made out to be as if that's the significant thing. 17M just provides the baseline of "normal". Tons more data isn't needed to get that right. 170M wouldn't make a difference. I bet 1.7M wouldn't make a big difference either. What we really need to know right now is how the Covid deaths behave. All that this offe…

I have to admit, the title does sound misleading in this regard, and (to me) even more so the tweets advertising the paper as per the submission.

You misunderstand. The only reason the study has enough power to make statements about the relative risk of, say, obesity independently of age, sex, and ethnicity is because there are 17 million patients to use as "controls".

Down voted for helping others. HN...you've lost your mind. Your sense of community is an embarrassment.

A copy-paste of the bio from Wikipedia would be more helpful than a DDG search link.

For you perhaps. But I didn't see value in imposing my will on others. In fact, I looked at a few of the articles in that DDG SERP.
