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
An 81-year-old man with lower extremity arteriosclerosis obliterans presented with massive hemoptysis. Computed tomography revealed an enlarged ectopic right bronchial artery originating from the concavity of aortic arch, prompting the decision to perform bronchial artery embolization (BAE). Due to occlusion of bilateral femoral and left subclavian arteries, transfemoral or left transbrachial access was not feasible; therefore, right transbrachial access was chosen. BAE was successfully completed, and antiplatelet and anticoagulant therapy was subsequently initiated. No recurrence of bleeding was observed at the time of this report, with a follow-up of at least 20 months. This is the first reported case of transbrachial BAE targeting an ectopic bronchial artery arising from the concavity of the aortic arch, achieved by modifying coronary catheterization techniques with the use of the Ishikawa catheter.
