* The functional status composite score ranges from 0 to 22, with higher scores indicating better function. Delirium severity was defined as mild if CAM-S maximum score ≤9 and severe if CAM-S maximum score >9 (CAM-S score 9 was the medial score of patients with delirium). The nodes and vertical bars indicate the means and 95% confidence intervals of the functional status composite score at each assessment that were estimated from a linear mixed-effects regression model that adjusted for age, sex, and Charlson Comorbidity Index.
