  1. TNM tumor node metastases, BMI body mass index, EE energy expenditure
  2. aContinuously variables were tested with Student t-test. Categorical variables were tested by the Fischer exact test (two-sided)
  3. bEstimated energy expenditure from the physical activity monitor SenseWear Armband Mini (BodyMedia, Pittsburgh, Pennsylvania, USA) (SWA)
  4. cThe maximal strength of hand grip (kg) was recorded. For women and men, a 40 kg- and 80 kg-spring was used, respectively
