Lower Hemoglobin Concentration Is Associated with Retinal Ischemia and the Severity of Diabetic Retinopathy in Type 2 Diabetes

Table 4

General and hematological variables that showed statistically significant differences in the comparison between groups according to the presence or absence of CSME in the group patients with diabetic retinopathy.

	Diabetic retinopathy without CSME; ()	Diabetic retinopathy with CSME; ()	value
Urinary albumin: creatinine ratio, mg/g	9.2 [5.1–22.0]	23.3 [9.4–68.8]	<0.001
Systolic BP (mm Hg)	141 (129–154)	148 (135–165)	0.0337
Hemoglobin (gr/dL)	13.8 [13.0–14.9]	13.2 [12.6–14.1]	0.047
Erythrocytes (×10^12/L)	4.7 [4.5–5.0]	4.6 [4.3–4.8]	0.019
Hematocrit (%)	41.3 [39.2–43.5]	40.3 [38.3–42.0]	0.047
