Incidence Rates of Dementia by Diabetic Retinal Disease Status

	No. of Dementia cases	Total Person Years	Incidence Rate per 10,000 Person Years (95%CI)
No diabetic retinal disease N=27953	4787	186622.5	256.5 (249.2, 263.7)
Diabetic retinal disease N=2008	386	11743.1	328.7 (295.9, 361.4)
Proliferative retinopathy only N= 502	91	2837.4	320.7 (254.8,386.6)
Diabetic macular edema only N=1014	220	6025.2	365.1 (316.9, 413.4)

For the calculation of the incidence density rate of the groups with only DPR or only DME, patient with respectively DME and DPR were excluded.
