Association Analysis and Exploratory Mediation Study of the Stress-Induced Hyperglycaemia Ratio and Glycaemic Ratio Indices with Diabetic Retinopathy in Patients with Type 2 Diabetes (opens in new tab)

ObjectiveDiabetic retinopathy (DR) is a major microvascular complication of type 2 diabetes mellitus (T2DM), and traditional glycaemic control indicators struggle to comprehensively predict its risk. This study aims to investigate the association between the stress hyperglycaemia ratio (SHR), fasting blood glucose/glycated hemoglobin (FBG/HbA1c), postprandial 2-h glucose/glycated hemoglobin (P2hBG/HbA1c) with DR in T2DM patients, and the mediating effects of non-high-density lipoprotein chole...
