Is systolic interarm blood pressure difference associated with the presence of diabetic retinopathy in patients with type 2 diabetes?
Systolic interarm blood pressure difference ⩾5 mmHg is associated with diabetic retinopathy and may serve as a surrogate marker for vascular complications in patients with type 2 diabetes.
The association between interarm blood pressure difference and the presence of diabetic retinopathy emerged even for systolic interarm blood pressure difference ⩾5 mmHg without interaction of systolic blood pressure. Systolic interarm blood pressure difference should be considered a surrogate marker for vascular complication in patients with type 2 diabetes.
