BODE Index (COPD prognosis)
BODE index (Celli 2004): BMI, FEV1 % predicted, mMRC dyspnea, and 6-minute walk distance mapped to a 0-10 score and quartile survival.

Example
- Body-mass index
- 24 kg/m^2
- FEV1
- 45 % predicted
- mMRC dyspnea grade
- 2 — walks slower than peers, or stops for breath at own pace
- 6-minute walk distance
- 300 m
Result: BODE index 4 of 10 (quartile 3-4): ~67% approximate 4-year survival (Celli 2004 quartile 2).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Points (0-10)
- BMI <= 21 = 1; FEV1% >= 65 = 0, 50-64 = 1, 36-49 = 2, <= 35 = 3; mMRC 0-1 = 0, 2 = 1, 3 = 2, 4 = 3; 6MWD >= 350 = 0, 250-349 = 1, 150-249 = 2, <= 149 = 3.
- 4-year survival
- Approximate by quartile: 0-2 ~80%, 3-4 ~67%, 5-6 ~57%, 7-10 ~18% (Celli 2004 cohort).
