An Unusual Pulmonary Vascular Connection Encountered During Right Upper Lobectomy.
Article in Interdisciplinary cardiovascular and thoracic surgery, 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
backgroundPulmonary vascular variations may complicate thoracic surgery, particularly video-assisted procedures, where such anomalies increase the risk of bleeding. CASE PRESENTATION: We report a 77-year-old female undergoing right upper lobectomy for invasive mucinous adenocarcinoma. Imaging revealed a 2 cm posterior right upper lobe nodule with low FDG uptake. Histology showed mixed adenocarcinoma and large-cell neuroendocrine carcinoma (stage IA). Intraoperatively, a vascular connection consistent with an arteriovenous fistula between the superior pulmonary vein and the interlobar pulmonary artery was identified and ligated.
conclusionsRecognition of rare pulmonary vascular anomalies through careful preoperative imaging and intraoperative assessment is essential to minimize surgical complications and ensure safe thoracic resection..
