The Gender-Age-Physiology (GAP) model is a validated, baseline-risk prediction model for
mortality in idiopathic pulmonary fibrosis. Longitudinal variables have been shown to …

Background The gender–age–physiology (GAP) model was developed to predict the risk of
death. Comorbidities are common in idiopathic pulmonary fibrosis (IPF) and may impact on …

Rationale: Mortality prediction is well studied in idiopathic pulmonary fibrosis (IPF), but little
is known about predictors of premortality disease progression. Identification of patients at …

Introduction The gender-age-physiology (GAP) index is an easy-to-use baseline mortality
prediction model in idiopathic pulmonary fibrosis (IPF). The GAP index does not incorporate …

Background Idiopathic pulmonary fibrosis (IPF) is a progressive interstitial pneumonia with
an unpredictable course. The aims of this study were to retrospectively re-evaluate a cohort …

Rationale: Several predictors of mortality in patients with idiopathic pulmonary fibrosis have
been described; however, there is a need for a practical and accurate method of quantifying …

Background The clinical course of idiopathic pulmonary fibrosis (IPF) shows great inter-
individual differences. It is important to standardize the severity classification to accurately …

BACKGROUND No study has determined whether the risk of mortality predicted by the GAP
(gender, age, and physiologic variables) model matches the observed mortality from …

Background Idiopathic pulmonary fibrosis is a progressive lung disease with variable
course. The Gender-Age-Physiology (GAP) Index and staging system uses clinical variables …

Background The clinical course of idiopathic pulmonary fibrosis (IPF) varies widely.
Although the GAP model is useful for predicting mortality, survivals have not yet been …
