  1. eGFR estimated glomerular filtration ratio, HR hazard ratio, CI confidence interval
  2. Increased percent body fat mass (increased FM) was defined as percent body fat > 25% in males and > 30% in females
  3. Muscle wasting, i.e., reduction in skeletal muscle mass, was defined as appendicular skeletal muscle mass index < 7.0 kg/m2 in males and < 5.4 kg/m2 in females
