  1. Slopes of the regression lines relating V and D are provided. C, NDR, NPDR, and PDR are abbreviations for non-diabetic control, no clinically visible diabetic retinopathy, non-proliferative diabetic retinopathy, and proliferative diabetic retinopathy, respectively. Bold indicates statistical significance.
  2. aSignificant association between V and D.
  3. bAssociation between V and D significantly different than C (ref).
  4. *Unadjusted.
  5. **Adjusted for age, race, sex, mean arterial pressure, heart rate, hematocrit, and hemoglobin A1C.
