We performed a multiple linear regression analysis for FOIS at discharge, including age, gender, CRP, GNRI, Alzheimer’s disease, Parkinson’s disease, BMI, change in the ARS score, cerebral infarction, intracerebral hemorrhage, subarachnoid hemorrhage, FIM–T at admission, and the number of drugs prescribed at admission as covariates. This evidence concerns the gene CRP and early-onset autosomal dominant Alzheimer disease.
