As sarcopenia progressed, i.e., from normal to semi-sarcopenia, and then to sarcopenia, age increased (p < 0.001), nursing home placement and the preexisting CeVD and dementia were more common (p < 0.05), and SMI, HGS, WS, and Alb were lower (p < 0.001). The gene discussed is ALB; the disease is dementia.
