Survival curves based on skeletal muscle index (a), muscle density (b), subcutaneous fat index (c), visceral fat index (d), subcutaneous fat density (e) and visceral fat density (f). Patients with skeletal muscle index and muscle density below the thresholds had an increased mortality. Low subcutaneous and visceral fat index were also associated with an increased risk of dying. Finally, a high subcutaneous and visceral fat density also correlated with mortality
