Evaluating the role of American Thoracic Society/European Respiratory Society/Japanese Respiratory Society/Latin American Thoracic Society high-resolution CT-thorax usual interstitial pneumonitis imaging categories in selecting candidates for transbronchial lung cryobiopsy for undifferentiated interstitial lung disease, a retrospective study.

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: The utility of high-resolution computed tomography-thorax (HRCT) in predicting which subtypes of interstitial lung disease (ILD) require tissue diagnosis with transbronchial lung cryobiopsy (TBLC) is unclear. We aim to see if usual interstitial pneumonia (UIP) imaging categories can inform patient selection for TBLC in undifferentiated ILD. Methods: Retrospective study of 76 patients who underwent TBLC for undifferentiated diffuse ILD at a university hospital between 2017 and 2023. HRCT imaging was reviewed on each patient and categorised as per their American Thoracic Society (ATS)/European Respiratory Society (ERS)/Japanese Respiratory Society (JRS)/Latin American Thoracic Society (ALAT) UIP imaging pattern (definite UIP, probable UIP, indeterminate UIP or alternative diagnosis). Chart history/examination, pulmonary function tests, ILD blood-panel, bronchoscopy/bronchoalveolar lavage cellular results and multi-disciplinary team meeting (MDM) discussion were assessed to determine the pre-TBLC diagnostic consensus to include TBLC for further diagnostic accuracy. These were compared against post-TBLC MDM outcomes to confirm if TBLC altered diagnosis and management. Results: Diagnosis was changed in 43.4% (33/76) of cases post-TBLC. Significantly, TBLC altered the pre-TBLC diagnosis in 65% (13/20) in the indeterminate UIP HRCT category, 41.9% (13/31) in alternative diagnosis, 30% (6/20) in probable UIP and 20% (1/5) in definite UIP categories. There was a confirmed statistical difference between indeterminate UIP and probable UIP patients. TBLC led to a confirmed post-MDM diagnosis in 80.2% of cases, in keeping with international standards. Conclusions: TBLC is an effective diagnostic tool in those with indeterminate UIP HRCT patterns. When UIP/idiopathic pulmonary fibrosis (IPF) is felt more likely (probable UIP) on pre-TBLC HRCT, TBLC is less useful.
