GPT and dementia: Considering the high correlation between AST and ALT (0.886), and considering the trend, we excluded the ALT from logistic regression The ordered logistic regression confirmed that older age (odds ratio (OR): 1.02; 95% confidence interval (CI) 1.01–1.03), higher CCI (OR 1.088; 95%CI 1.005–1.18), presence of dementia (OR: 2.20; 95%: 1.30–3.73), and higher serum AST (OR: 1.002; 95% CI: 1.0001–1.004) and total bilirubin (OR: 1.09; 95% CI: 1.002–1.19) values were associated with a more severe clinical outcome (Table 2).
