Table 3 Logistic regression analysis of retinal microvascular parameters and Mild Cognitive Impairment status

From: Retinal microvascular parameters are not significantly associated with mild cognitive impairment in the Northern Ireland Cohort for the Longitudinal Study of Ageing

Retinal parameter Minimally Adjusted Fully Adjusted
OR 95% CI P-Value OR 95% CI P-Value

  1. Abbreviations: CRAE central retinal arteriolar equivalent, CRVE central retinal venular equivalent, AVR retinal arteriole/venular ratio, CI confidence interval, OR odds ratio, PX pixels. aRMPs were transformed into standardised Z-scores before inclusion in regression models. bTortuosity values were skewed and therefore log-transformed before inclusion in regression models. Minimally adjusted model: age and sex. Fully adjusted model: age, sex, alcohol consumption, smoking status, educational attainment, physical activity, history of cardiovascular disease, hypertension, triglycerides, diabetes, medication, mean arterial blood pressure, body mass index and high density lipoprotein. P < 0.05 was considered statistically significant
