Adjusted means (with standard errors) for Central Retinal Arteriolar Equivalent (CRAE) across periodontal status categories and diabetic status. PD: Periodontal diseases. Generalized linear models. Three categories model: healthy/gingivitis (reference) versus moderate PD versus severe PD. Healthy/gingivitis. Adjustment for propensity score, maximum level of adjustment. Diabetes free, n = 391; no PD/gingivitis, n = 151; moderate PD, n = 163; severe PD, n = 77; p for linear trend = 0.32. Diabetes mellitus, n = 66; no PD/gingivitis, n = 20; moderate PD, n = 31; severe PD, n = 15; p for linear trend = 0.03. All subjects, n = 457; no PD/gingivitis, n = 171; moderate PD, n = 194; severe PD, n = 92; p for linear trend = 0.13.
