Enhancing Risk Assessment in Patients with Diabetic Retinopathy by Combining Measures of Retinal Function and Structure.

There is a tendency for a positive structural result to increase risk and a negative structural result to decrease risk; however, the difference in these groups is of marginal significance: 2/6 groups have P values > 0.05, 3/6 are significant at the P ≤ 0.05 level, and only 1/6 is significant at the P ≤ 0.01 level.
