Interesting that it doesn't ask about blood pressure, which is a risk factor, or blood type, as there is fairly solid evidence that people with type A blood are at increased risk, while those with type O blood are protected.

in the model derivation they included "treated hypertension" as a possible independent variable. I suspect they did not have blood type information in the GP records on a majority of people in the cohort.
