Carinal Squamous Cell Carcinoma Causing Progressive Central Airway Obstruction: CT, FDG PET/CT, Bronchoscopic Pre- and Post-Debulking, and Pathologic Correlation.
Article in Case reports in radiology, 2026. 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
Primary tracheobronchial tumors are rare and are frequently diagnosed late because their presenting symptoms are nonspecific and may mimic more common respiratory conditions. We report a case of a 74-year-old man with a significant smoking history who presented with progressive dyspnea, cough, hemoptysis, and stridor, initially treated with multiple courses of antibiotics and corticosteroids, without improvement. Chest radiography was reportedly normal, but a contrast-enhanced CT demonstrated an endoluminal soft tissue mass centered at the distal trachea/carina with extension into the bilateral mainstem bronchi, causing near-complete obstruction of the left mainstem bronchus and moderate-to-severe narrowing of the right mainstem bronchus. Coronal FDG PET/CT demonstrated intense metabolic activity centered at the carina. Predebulking bronchoscopy confirmed a verrucous fungating carinal mass causing severe central airway compromise, whereas postdebulking bronchoscopy showed marked restoration of airway patency. Histopathologic evaluation established squamous cell carcinoma. This case highlights the diagnostic limitations of chest radiography and the essential role of CT, FDG PET/CT, and bronchoscopy in evaluating malignant central airway obstruction.
