Hubbard	Comparison of Digital and Film Grading of Diabetic Retinopathy Severity in the Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications Study	2011.0	9	.pdf	application/pdf	7707	794	61	Objective: To compare diabetic retinopathy (DR) severity as evaluated by digital and film images in a long-term DR were imaged, per the Early Treatment Diabetic Retinopathy Study (ETDRS) protocol, with both film and digital cameras. Conclusion: Digital and film evaluations of DR were comparable for ETDRS severity levels, DCCT/EDIC design outcomes, and major study conclusions, indicating that switching media should not adversely affect ongoing studies. After grading the digital images of 98 eyes (49 subjects) without standardized enhancement for tonal characteristics, the reading center performed a preliminary comparison of ETDRS retinopathy severity levels between digital and film gradings. Cross-tabulation of film and digital gradings of final Early Treatment Diabetic Retinopathy Study scale based on eye level of 310 subjects with gradable Cross-tabulation of film and digital gradings of final Early Treatment Diabetic Retinopathy Study scale based on person-level of 310 subjects with	./cache/work_wpgh5dhunnhi5f5dfcegw5jjxq.pdf	./txt/work_wpgh5dhunnhi5f5dfcegw5jjxq.txt
