  1. U Mann–Whitney test
  2. t-student test (CFS/ME: women pre test- fatigue vs. men pre test- fatigue, women post test- fatigue vs. men post test- fatigue)
  3. Cognitive function: Montreal cognitive assessment (MoCA). Cut-off point: 26. Mild Cognitive Deterioration (< 21)
  4. Global Index Attention and Perception (GIAP): Toulouse-Piéron test. 0 = No evaluable (abandons the test due to very high fatigue), 1 = Very low, 2 = Low, 3 = Medium, 4 = High, 5 = Very high
  5. Fatigue: Visual analogue scale (VAS). 0 mm = No fatigue, < 40 mm = Mild, ≥ 40 mm–< 70 mm = Moderate, ≥ 70 mm = Severe, 100 mm = Maximum
  6. Perception of cognitive effort: Borg modified scale. 0 = Nothing at all, 1 = Very, very light, 2 = Very light, 3 = Moderate, 4 = Something hard, 5 = Hard, 6 = Hard, 7 = Very hard, 8 = Very hard, 9 = Very hard, 10 = Very very hard
