It is worth noting that, in non-obese participants, after adjustment for confounding factors such as age, sex, HbA1c, smoking history, T2DM duration, BMI, systolic blood pressure, diastolic blood pressure, triglycerides, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, ALT, AST, GGT, and uric acid, the ORs of MALFD remained negatively associated with diabetic retinopathy but not with diabetic peripheral neuropathy (Table 5). This evidence concerns the gene GPT and diabetic retinopathy.
