Using Cox multivariate proportional hazards analysis, after adjusting for potential confounders, in model 1, several parameters, such as SPPB (functional capacity), albumin (nutritional biochemical parameter), and CRP (inflammation parameter), and in model 2, factors such as SPPB, CRP and %IBW (like muscular parameter), were significantly associated with the risk of all-cause mortality in CKD patients. The gene discussed is ALB; the disease is chronic kidney disease.
