Intraoperative left hepatic branch artery aneurysm rupture discovered during cholecystectomy: a case report of a rare and potentially lethal diagnosis.
Article in Journal of surgical case reports, 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
Hepatic artery aneurysm (HAA) is a rare but potentially lethal condition, accounting for ~20% of visceral aneurysms, with a reported rupture rate of up to 44%. Its pathophysiology remains incompletely understood, though risk factors include atherosclerosis, trauma, infection, connective tissue disorders, and iatrogenic causes. Clinical presentation varies from asymptomatic to abdominal pain, gastrointestinal symptoms, or biliary obstruction. Angiography-CT is the diagnostic modality of choice. Management is guided by symptoms, aneurysm size, and rupture status, ranging from observation to endovascular or surgical interventions. We report a case of hemoperitoneum due to a ruptured HAA that was incidentally discovered during a laparoscopic cholecystectomy.
