Register-based associations remain susceptible to residual confounding, care-use differences and measurement limitations. The study found associations with retinopathy and albuminuria but not higher stroke, cardiovascular disease or mortality risk in the diabetes groups. It does not test whether treating periodontitis prevents these complications.
