Comparison of Mean Arterial Pressure (MAP), Hemoglobin A1c (HbA1c), and Hematocrit (HCT) Among Groups

	Control	No DR	Mild NPDR	Moderate to
Metric	(N = 25)	(N = 28)	(N = 21)	Severe NPDR (N = 14)	PDR (N = 7)	P Value
MAP (mm Hg)	103 ± 14	102 ± 16	100 ± 11	103 ± 17	108 ± 15	0.80
HbA1c (%)	5.4 ± 0.47^a	7.0 ± 1.1	7.7 ± 1.4	8.0 ± 1.4	8.4 ± 1.6	<0.0001
HCT (%)	45 ± 4	43 ± 3^b	40 ± 5	43 ± 4	41 ± 5	0.001

Data presented in control, no diabetic retinopathy (no DR), mild nonproliferative diabetic retinopathy (mild NPDR), moderate to severe NPDR, and proliferative diabetic retinopathy (PDR) groups.

Bolded values indicate P < 0.05. Superscripts represent groups that had missing HbA1c or HCT data and thus a lower N value of subjects in that group,

N = 23.

N = 27.
