Severe coronary artery spasm associated with endobronchial cytologic sampling, bleeding, and endobronchial epinephrine administration during bronchoscopy: A case report.

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
Although coronary artery spasms during bronchoscopies are rare, they can cause severe cardiac complications. An 84-year-old man receiving enzalutamide for prostate cancer underwent a bronchoscopy for the diagnostic evaluation of a 20-mm ground-glass nodule in the left S3 segment, detected on chest computed tomography. After endobronchial cytologic sampling using a curette, transient ST-segment elevation was observed on electrocardiography. Bleeding from the left B3 bronchus was controlled by local instillation of a few millilitres of 1:100,000 epinephrine. Shortly afterward, hypoxaemia, hypotension, bradycardia, and recurrent ST-segment elevation developed. Echocardiography revealed inferior and right ventricular wall hypokinesis, whereas coronary angiography revealed no significant stenosis, confirming a coronary artery spasm. The patient recovered with conservative treatment. This case indicates that coronary artery spasms associated with endobronchial cytologic sampling, bleeding, or local epinephrine use may occur during bronchoscopy, and that ST-segment elevation during the procedure may serve as an early indicator of coronary spasm requiring prompt action.
