  1. BMI: Body Mass Index; SNS: Subjective Nutritional Score; SNS (M): Muscle component of Subjective Nutritional Score MAC: Mid Arm Circumference; MAMA: Mid Arm Muscle Area; TSF: Triceps Skinf Fold; CRP: C Reactive Protein; 6MWT inability: inability to perform the six minutes walking test; ABI: Ankle Brachial Index; High stress (disease): High degree clinical stress according with the presence of hyper-metabolic, hyper-catabolic disease.
  2. Short term survival was analyzed by Chi-square test with correction for continuity (X2c) and long term survival by Kaplan and Meyer survival curves compared by long-rank test. OR: Odd ratio, CI: 95% confidence interval; HR: Hazard ratio.
