Fig. 3From: A cluster-based analysis evaluating the impact of comorbidities in fibrotic interstitial lung diseaseRate of FVC decline over 2 years from the time of ILD diagnosis by cluster. IPF cluster 4 had significantly greater rate of lung function decline compared to cluster 1 (p = 0.03). There was no statistically significant difference in rate of lung function decline between clusters in other ILD subtypes. Abbreviations: FVC forced vital capacityBack to article page
