Figure 2. Cognitive performance in participants with and without glaucoma. Violin plots of the adjusted predicted values of z-scores of (A) delayed word recall test, (B) verbal fluency task, (C) trail making test, and (D) global cognitive composite score according to glaucoma status. Significant results were found only for verbal fluency task (B). Multiple linear regression models with robust covariance were employed, with adjustment for age, sex, ethnicity, education, ideal smoking status, ideal physical activity status, hypertension, diabetes, ideal cholesterol status, presence of cardiac conditions, body mass index, excessive alcohol use, presence of thyroid dysfunctions, and presence of depression.
