The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Breathlessness grade | 2 — Walks slower than peers / stops for breath |

- COPD assessment：mMRC ≥ 2 indicates more symptoms in the GOLD ABE assessment.
| Breathlessness grade | 0 — Only with strenuous exercise |
