Especially in the Kaplan–Meier curve for CKD patients with hypoalbuminaemia (albumin < 35 g/dL), the one-year survival was significantly different according to MPI group, with a higher MPI showing significantly higher mortality (p < 0.001, survival for hypoalbuminaemia patients with MPI-1: 82%, MPI-2 50%, MPI-3: 24%; Figure 5b). Here, ALB is linked to Hypoalbuminemia.
