Fig. 3From: Associated risk factors in the early stage of diabetic retinopathyComparisons of the retinal capillary density (RCD) in diabetic subgroups grouped by major risk factors with controls on OCT-A images in the superficial and deep retinal capillary layers (SRCL and DRCL). The RCDs in SRCL and the DRCL of diabetic subgroups grouped by major risk factors were lower than those of the control group. In addition, the RCDs in the diabetic groups with age > 55y (a), HbA1c > 7% (b), LDL-C > 3.1 mmol/L (c), or BUN > 8.2 mmol/L (d) were also decreased compared to those of the other groups. *P < 0.05, **P < 0.01, ***P < 0.001Back to article page
