Polygenic risk of idiopathic pulmonary fibrosis and COVID-19 severity.
Article in ERJ open research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: A shared genetic component between coronavirus disease 2019 (COVID-19) and idiopathic pulmonary fibrosis (IPF) has been described based on analyses of individual risk variants. Here we used a whole-genome polygenic risk score (PRS) approach to further evaluate age- and sex-stratified genetic overlap between IPF and severe COVID-19 to give insight into shared biological mechanisms that might both inform therapeutic strategies for both diseases. Methods: We used results from the largest genome-wide association study of clinically defined IPF risk (4125 cases/20 464 controls) and individual-level data from the SCOURGE European study of COVID-19 (5968 cases/9056 controls). We calculated IPF PRSs and assessed their association with COVID-19 severity, stratified by age and sex. We performed replication in an independent dataset of Latin-American patients (1625 cases/1887 controls). Enrichment and pathway-specific PRS analyses were performed to study biological pathways associated with COVID-19 severity. Results: IPF PRSs were significantly associated with COVID-19 hospitalisation and severe illness in Europeans and replicated in a Latin-American cohort. The strongest association was found in <60 years patients, especially among younger males (p=6.39×10 Conclusions: The study indicates age and sex-dependent genome-wide genetic overlap between IPF and severe COVID-19 and highlights specific shared biological mechanisms underlying both conditions. This could also imply that individuals with a high IPF genetic risk are at an overall increased risk of developing lung sequelae resulting from severe COVID-19.
