  1. AA, MAP and HbA1C are abbreviations for African American, mean arterial pressure and hemoglobin A1C, respectively. 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. The ± symbol refers to standard deviation (SD).
  2. P-values derived by Chi square (a) or ANOVA (b).
