Linear mixed-effects models and Cox proportional hazard models were used to determine forced vital capacity (FVC) slopes and 5-year transplant-free survival, respectively, by ILD diagnosis and UIP radiological pattern. Secondarily, we examined FVC and survival by diagnosis and radiological fibrosis quantified by data-driven texture analysis (DTA) in the PFF-PR. Models were adjusted for age, sex, smoking and antifibrotic and immunosuppression medication use.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The proportions of idiopathic pulmonary fibrosis (IPF), fibrotic hypersensitivity pneumonitis (FHP) and connective tissue disease (CTD)-ILD were the following for PFF-PR (70%, 11%, 19%) and meta-cohort (21%, 32%, 47%). In the PFF-PR, CTD-ILD with UIP CT pattern was associated with slower FVC decline (\u221234.4\u2009mL\/year) compared with IPF (\u2212158.4\u2009mL\/year) and longer transplant-free survival (HR 0.50, 95%\u2009CI 0.29 to 0.85). This was replicated in the meta cohort for FVC (\u221253.1 vs \u2212185.9\u2009mL\/year, p&lt;0.0001) and survival (HR 0.38, 95%\u2009CI 0.27 to 0.53). A similar pattern was seen using DTA to objectively categorise patients into higher and lower radiological fibrosis. Between IPF and FHP-UIP, FVC decline was not significantly different in the PFF-PR (\u2212203.4 vs \u2212158.4\u2009mL\/year, p=0.58) and meta-cohort (\u2212124.0 vs \u2212185.9\u2009mL\/year,
