Table 3. Rates of completed eye examination among cohorts.

Rates of a completed eye examination were recorded at 3, 6, and 12 months after the index primary care visit. The reference cohort was a historic control, which represents attendance at a recommended eye clinic visit at the same time intervals. The proportion of total patients who attended or did not attend a recommended eye exam was compared between cohorts for each time interval using Fisher’s Exact test. Values in bold indicate significant results. rDED = referable diabetic eye disease; vtDED = vision threatening diabetic eye disease.
