In the multivariable Cox proportional hazards regression analyses, the factors confirmed as the independent variables associated with all-cause death in all the study patients were older age, female sex, no prescription of ACEIs or ARBs, anemia, low albumin levels, high BUN levels, and low estimated glomerular filtration rate (eGFR) (eTable 1 in the Supplement). This evidence concerns the gene ALB and anemia (phenotype).
