or not. 16.5% of beds are (allegedly) occupied by diabetics, of whatever type. It does not then follow that those beds are being occupied for diabetic related conditions.
and I am not sure about this bit being mathematically correct:
I assume you subtracted the 6% who are diabetic from the 16% occupying beds. However, that is nonsense mathematically and statistically.
Of the 16.5% you mention, 100% of them are (allegedly) diabetic, so where does the idea that 10% of those are there for diabetic related conditions? The cause of the diabetics occupying the beds is an unknown factor. We cannot extrapolate a figure for the ones having diabetic complications from the information given.
