Table 1 Variables and Point Values Used for the Computation of the Body-Mass Index, Degree of Airflow Obstruction and Dyspnoea, and Exercise Capacity (BODE) Index according to [24].*

From: BODE index versus GOLD classification for explaining anxious and depressive symptoms in patients with COPD – a cross-sectional study

Variable Points on the BODE Index
  0 1 2 3
FEV1%predicted ≥ 65 50–64 36–49 ≤ 35
Distance walked in 6 min (m) ≥ 350 250–349 150–249 ≤ 149
MMRC dyspnoea scale‡ 0–1 2 3 4
Body mass index§ >21 ≤ 21   
  1. * The cut-off values for the assignment of points are shown for each variable. The total possible values range from 0 to 10. FEV1%predicted denotes forced expiratory volume in one second as a percentage of the predicted value.
  2. † The FEV1%predicted categories are based on stages identified by the American Thoracic Society.
  3. ‡ Scores on the modified Medical Research Council (MMRC) dyspnoea scale can range from 0 to 4; 0 – "Not troubled with breathlessness except with strenuous exercise"; 1 – "Troubled by shortness of breath when hurrying on the level or walking up a slight hill"; 2 – "Walks slower than people of the same age on the level because of breathlessness or has to stop for breath when walking at own pace on the level"; 3 – "Stops for breath after walking about 100 yards or after a few minutes on the level"; 4 – "Too breathless to leave the house or breathless when dressing or undressing"
  4. § The values for body-mass index were 0 or 1 because of the inflection point in the inverse relation between survival and body-mass index at a value of 21.
