// It's nothing to do with Iceland. Very different situations.//
I dont see if there is a difference in X or Y between the two countries, it is always gonna be associated with population - because Iceland is forever few and we are forever many. statistical quirk.
the only event distinguishable is if there is no difference in C between UK and iceland in which case you can conclude population doesnt play a part.
technical point - probably unsuitable for the braynes of AB
AND whilst you were discussing I accessed
https://www.bmj.com/content/370/bmj.m3489
streamed webinar on Long Covid. It is long at 75 mins,
and can be summed up in 15s as
1.20% pts have debilitating signs at one month
2.and 2% of patients go onto 3 months
3.wait and see as there is very little else to be done
4. who will progress? usual suspects old hypertensive and diabetic.
and that is just about it
