Factors such as institutionalization at discharge, functional dependence, immobilization, oxygen therapy, urinary catheterization, nasogastric tube placement, sodium levels, albumin levels, and C-reactive protein levels, as well as clinical history variables including cognitive impairment, prior delirium, substance use, and alcohol consumption, did not demonstrate statistically significant associations with mortality risk in this analysis (see Supplementary Material Table S1). This evidence concerns the gene ALB and Cognitive impairment.
