This is a CDC study from the US. Having had a quick look it is not quite straightforward to compare it with the studies by the group of Jonathan Valabhji, which I've discussed earlier in this thread. The papers are available at
https://www.england.nhs.uk/publicat...es-and-covid-19-related-mortality-in-england/.
One of the main result of the CDC study is: "the most common underlying health conditions were cardiovascular disease (32%), diabetes (30%), and chronic lung disease (18%). Hospitalizations were six times higher and deaths 12 times higher among those with reported underlying conditions compared with those with none reported."
Where as the main result of the Valabhji paper include
1) the odds of dying for people with T1 was 3.5 times that of people without diabetes.
2) the odds of dying for people with T2 was 2.0 times that of people without diabetes.
The CDC study lumps all conditions together and comes up with a risk of death being 12 times higher. You naively might say that the death risk for all diabetes people in the US is 30% of 12 times that of healthy people, i.e. scaling by fraction of the people with diabetes compared to all conditions. However you should not do this as this assumes that the increase in risk is the same for all conditions, which is clearly not the case. For example if people have more than one condition the risk increases. For a comparision would also nee to take into account differences in the populations.
In conclusion I can't find the information in the CDC study to make a 1:1 comparison on covid death risk for diabetics with the Valabhji study.
