Localized Tracheobronchial Transthyretin Amyloidosis Diagnosed After Hemoptysis: A Case Report.
Article in Respirology case reports, 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
Pulmonary involvement in transthyretin amyloidosis (ATTR) is rare, and tracheobronchial involvement is particularly uncommon. We report a case of wild-type ATTR amyloidosis presenting with hemoptysis in a 66-year-old woman with dyspnea. Chest computed tomography revealed bronchial wall thickening and infiltrative opacities. Bronchoscopy showed irregular mucosal lesions extending from the trachea to both bronchi. Histopathological examination of bronchial biopsy specimens showed Congo red-positive deposits, and immunohistochemistry confirmed transthyretin, establishing the diagnosis of ATTR amyloidosis. Systemic evaluation and genetic testing excluded systemic and hereditary disease, leading to a diagnosis of localized wild-type ATTR. Bronchial aspirate cultures yielded
