Clinical Outcome Prediction by High-Resolution Computed Tomography and Echocardiography Assessment of Pulmonary Hypertension in Patients with Bronchiectasis.
Article in Tuberculosis and respiratory diseases, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundTo evaluate the association between pulmonary hypertension and hospital admission rates in patients with bronchiectasis.
methodsWe retrospectively analyzed data from 130 bronchiectasis patients at the National Medical Center, Korea (November 2012 to October 2022). Pulmonary hypertension was evaluated using high-resolution computed tomography (CT) and echocardiography. Patients were categorized into two groups based on the diameter of the main pulmonary artery (mPA). Logistic regression analysis was performed to identify risk factors associated with hospitalization.
resultsForty patients had suspected pulmonary hypertension on echocardiography. A higher percentage of patients with mPA diameter >29 mm (n=61) had a history of previous exacerbations, elevated echocardiographic parameters related to pulmonary hypertension, and reduced lung function, compared to those with mPA diameter ≤29 mm (n=69). In univariate analysis, the hospitalization group showed increased mPA diameter; pulmonary artery to aorta ratio; involvement of lung lobes, cavities, and nodules; and increased systolic pulmonary artery pressure and peak tricuspid regurgitation velocity. In multivariate analysis, mPA diameter >29 mm (adjusted odds ratio [OR], 2.47; 95% confidence interval [CI], 1.14 to 5.32) and the involvement of more than two lobes (adjusted OR, 2.57; 95% CI, 1.14 to 5.77) were significant risk factors for hospitalization.
conclusionThe CT parameters demonstrated comparable accuracy to models that incorporated echocardiographic data to predict hospitalization in bronchiectasis patients.
