An Adult Case of Unilateral Left Pulmonary Artery Agenesis Presenting with Hemoptysis.
Article in Internal medicine (Tokyo, Japan), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 artery agenesis (PAA) is a rare congenital vascular anomaly usually diagnosed during infancy. We herein report a 67-year-old man with PAA manifesting as massive hemoptysis. Contrast-enhanced computed tomography of the chest revealed the diagnosis of PAA, which we speculated to have resulted in the present event. Detailed angiography provided more accurate information on the pulmonary vasculature and collateral circulation, which helped us plan tailored treatment. Although very rare, we must consider the possibility of PAA in adults with unexplained hemoptysis.
