A Multinomial Logistic Regression model including age, gender and years of education as co-variates was used to analyse group differences in past ophthalmological pathologies and treatments. For each comparison, the first listed group (Dementia, MCI or SCD) acted as reference. Statistical significance was set-up at p < 0.05.
AMD = age-related macular degeneration; CI = confidence interval; MCI = mild cognitive impairment; OR = odds ratio; SCD = subjective cognitive decline.
