    Pearls/Pitfalls
    Why Use

    1, 2, and 3-year prognostication for IPF patients needing lung transplantation.

    • The GAP index is more sensitive, but less specific, than the the du Bois Score for predicting mortality.
    • The external validation concludes that the GAP index correlates well with 1-year mortality but NOT 3-year mortality.

    Simple, externally validated, scoring system using readily available baseline parameters.
