Table 3 Logistic regression controlling for potential confounding of the association between delirium and biomarkers in patients without dementia. Adjusted by age, gender, APACHE II (Acute Physiology and Chronic Health Evaluation II), Barthel ADL (Activities of Daily Living) and CCI (Charlson Comorbidity Index) scores

From: Increased CSF levels of aromatic amino acids in hip fracture patients with delirium suggests higher monoaminergic activity
