Objective:

To analyze the association between chronic obstructive pulmonary disease (COPD) severity and life expectancy.

Approach:
    Key Findings:

    Interpretation:

    Remove this section.

    Limitations:
    • COPD and severity were based on baseline spirometry, not updated during follow-up.
    • The study could not account for incident COPD or medication use.
    • Smoking status was self-reported and assessed only at baseline.
    • Estimates in older age groups may be affected by survivor bias.
    Conclusion:

    Revise to state that the study highlights the association without implying causation.
