From the link:
“...Initially, Denmark and Sweden had similar epidemic trajectories, suggesting similar levels of infection seeding in each country. Following the introduction of controls between March 13th and 18th, Denmark’s epidemic flattened more rapidly than Sweden’s, and by August Sweden had a five-fold higher mortality than Denmark. The UK trajectory differed from those Scandinavian countries in its higher early mortality, suggesting earlier or greater infection seeding. Nevertheless, despite its higher infection prevalence prior to the introduction of controls, by August the UK’s cumulative mortality was similar to Sweden’s...”
I see no mention in that research of the many and varied ‘risk factors’ that can shew a death rate dramatically. At best, looks to be very shoddy research.
I have covered in prior posts about the very high death rates in Swedens dark-skinned immigrant populations.
Remember, white skin evolved to make full use of poor sunshine conditions with the exception being the eskimos who were able to get their vitamin D, and other nutrients, from their extreme meat diet.
England also had a very high dark-skinned death rate.
As to Denmark and vitamin D. They attended to the issue over 10 years ago. Especially targeting the “dark-skinned immigrants”. Unfortunately, the link wont let me do the polite thing and post a quote. The reference is paragraph six:
