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

Table 2

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