Idiopathic pulmonary fibrosis in the UK: findings from the British Thoracic Society UK Idiopathic Pulmonary Fibrosis Registry.
Observational study in BMJ open respiratory research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectivesIdiopathic pulmonary fibrosis (IPF) is a progressive interstitial lung disease (ILD) and the most common idiopathic interstitial pneumonia. The UK IPF Registry was established in 2013 to collect data pertaining to clinical features, therapeutic approaches and outcomes. From February 2023, the Registry expanded to include any ILD with evidence of fibrosis.
designThe UK IPF Registry is a national, multicentre observational registry, including both prospective and retrospective data of patients with IPF in secondary or tertiary care. Cases eligible for inclusion were those with a diagnosis of IPF, presenting at participating centres from January 2013.
resultsBetween January 2013 and February 2023, 5052 IPF cases were registered from 64 participating centres. There was a male preponderance (77.8%) with mean±SD age of 74±8.1 years, 66% were ex-smokers and 76% had at least one comorbidity. Over a third (36.7%) experienced symptoms for more than 24 months prior to their first clinic visit. The majority of cases were discussed at a multidisciplinary team (MDT) meeting and the most common radiological patterns at presentation were probable (54.6%) and definite (42.7%) usual interstitial pneumonia. There was a reduction in surgical lung biopsies from 14% in 2013 to 5.5% in 2022. Antifibrotic therapy prescription rose from 36.0% in 2013 to 55.9% in 2023. The use of nintedanib (approved by National Institute of Clinical Excellence in January 2016) rose from 6.7% in 2013 to 31.5% in 2022 and pirfenidone (approved in April 2013) was initially used in around a third of cases before dropping to between 16.8% and 24.9% after nintedanib was approved.
conclusionThese data reflect clinical practice across the UK and it is intended the data will have a role in informing the future of IPF care and providing a model for benchmarking, ultimately increasing knowledge and improving clinical care for this devastating disease.
