From: Dietary glycemic index and retinal microvasculature in adults: a cross-sectional study
Multivariate analysis. Retinal arteriolar-venular index (AVI), retinal arteriolar caliber and retinal venular caliber by tertiles of glycemic index (GI). Model adjusted for age, gender, total energy intake, body mass index (BMI), systolic blood pressure (SBP), antihypertensive drugs, antidiabetic drugs and lipid-lowering drugs. Tertiles (T) GI: T1 (Lowest through 45.98); T2 (45.98 through 50.52); T3 (50.52 through Highest). AVI differences by tertiles of GI: p = 0.033 between T1 and T3, p = 0.031 between T2 and T3. Post-hoc contrasts were performed by the Bonferroni test
