There will probably have been multiple possible certifications that fulfilled that requirement. Which risk factors were mentioned/left out? The same applies to contributing factors.
Take a fatal heart attack. You cannot just say cardiac failure, but you can if you qualify it with a cause, such as coronary artery disease. That is all you need, but you could add cigarettes/diabetes/obesity/high cholesterol, or you could leave all those out, or just mention some of them.
And Covid increases the risk of clots in the legs/lungs (DVT/PE), cardiac inflammation and rhythm problems, strokes, lung inflammation and pneumonia and so on - and these do not necessarily occur only during the initial acute stage. So when do you put Covid on the certificate, and when do you leave it out? And if you include it, and let the Coroner know, what does he say? And if you decline to do a certificate, will the Coroner just do the certificate himself - including/leaving out Covid? Or will he hold an inquest?
So many possible variations, so many possible opinions - differences do not necessarily mean deceit, yet all these differences will add up. Hence my wish to see the full Covid numbers, not just the 28 day numbers.
