*Adjusted for variables including age, sex, smoking status, duration of diabetes, glycated hemoglobin, mean arterial blood pressure, fasting blood sugar, eGFR, creatinine, total cholesterol, BMI, intraocular pressure, and spherical equivalent.

BMI, body mass index; CAVI, cardio-ankle vascular index; eGFR, estimated glomerular filtration rate; FAZ, foveal avascular zone; GC-IPL, ganglion cell-inner plexiform layer; logMAR, logarithm of the minimum angle of resolution; RNFL, retinal nerve fiber layer.
