I suspect they were clutching at straws. Linear regression is sensitive to extrema, so BMI*yr potentially moves some datapoints around enough to get the 0.98 regression coefficient. Nevertheless, the fit is pretty awful, and correlation does not equal causation.

Even worse, I think they fudged the data. I digitized the superspreader datapoints and got a similar regression line, but R^2 = 0.0884, which is essentially no correlation. Image I used and spreadsheet attached. I used to digitze

Cool digitization tool. Yes, I believe your r^2 =0.0884 a lot more than their r^2 = 0.98. And yet this is a peer-reviewed article in a prestigous journal (PNAS - an initialism, not an acronym). I can't help but wondering if we're missing something somehow. Too bad we can't ask the authors to explain how the heck they came up with their number.

Having two members of the family with PhD's in the bio stuff I suspect it won't pass an engineer's sniff test on data spread.
 
They might have used the 'rejection of outliers' trick.
 
The only thing that is clear to me is that anyone older then 25 years old or with a BMI over 22 can be a super spreader.
2/3 of the population in most countries would probably be in this group.
Since there is people in the same BMI-year that are and are not super spreaders, I have a hard time to see what benefits there would be in showing it with a Unit like this.
A 65 year old with BMI 25 (normal) would be at 1625 BMI-years equally a 40 year old with a BMI 40.

Is the colloquial understanding of "Super Spreader" still acceptable?
A Super Spreader Event: A large public event such as a political rally or a sports event with no mask mandate or social distancing protocol. May be called a Super Spreader event.
A person who organizes or causes such an event to be organized may be called a Super Spreader.
A person who has unknowingly contracted COVID and continues to socialize while ignoring mask and social distancing protocols may be foolish.
A person who knows that they have contracted COVID and continues to socialize while ignoring mask and social distancing protocols may be characterized as a Super Spreader.

Super spreader has other meanings in Scottish referring to a female....

And high BMI is not a problem to your average Scottish bloke. More by lack of choice than anything else with the local lasses
 
If you like to hear my comment, come to the pub, I will tell you.
Wellcome back Alistair!

I get a lot of BMPs of curves where we need to get actual numbers, so this tool has been a serious improvement. The only issue I have now is that people don't always use sufficiently contrasting colors in their graphs ;-)

That's sad. I heard the 'try and give everybody one shot strategy' is working pretty bad against the new strain. The 'buy up all the vaccine and bribe the reluctant' strategy seems to be working well in the states.
 
There is folk who have had both shots plus the two weeks starting to die.

It was stupid not restricting flights back from India
 
What do you mean starting to die? The daily deaths for the entire UK are in single digits. Those are good numbers.
 
There is people who have had double shot over two weeks ago dying of covid again.

Not many but with the r rate well over 1 it's expected to rapidly increase again
 
> The 'buy up all the vaccine and bribe the reluctant' strategy seems to be working well in the states.

I'm not sure about the "buying up" part but the "bribe the reluctant" part is not working so great (graphic below from here). If you consider people with one dose as an indication of recent progress, we're not doing so well recently. There is a very strong anti-vaccine sentiment among certain segments and I have seen it firsthand in roughly half of my coworkers. I have mentioned in another thread it seems likely to me that we will see a UK-like surge here in the US within a month or two. I'll be watching uk closely as indication of what might be coming here, hoping their surge is not too bad.
