Coeliac trunk origin of bilateral inferior phrenic arteries.
Article in Frontiers in surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
Introduction: The bilateral inferior phrenic arteries supply the diaphragm, the suprarenal glands and the abdominal oesophagus. They typically originate from the abdominal aorta, superior to the coeliac trunk origin, and ascend to the inferior surface of the diaphragm. Variations in their anatomy are common and may contribute to hepatocellular carcinomas' vascularisation or increase the risk of iatrogenic injury during abdominal procedures. Existing studies are geographically limited and restricted to non-European populations. To date, no published data describing inferior phrenic arterial variations within a Scottish population. This study aims to investigate the origin, course and branching patterns of the inferior phrenic arteries in Scottish cadavers. Methods: Six formalin-embalmed human cadavers (mean age 87.3 years) from the Anatomy, Edinburgh Medical School, regulated by the Human Tissue (Scotland) Act 2006. The abdominal region was dissected to reveal the abdominal aorta and its branches. The origin, course and branches of the left and right inferior phrenic arteries were observed and documented. Results: Bilateral inferior phrenic arteries from two female donors ( Conclusion: Inferior phrenic arteries with a coeliac trunk origin were found in a third of the Scottish cadaver samples. Knowledge of these variations is crucial to minimising incomplete hepatocellular carcinoma embolization and iatrogenic injuries during upper abdominal surgeries, possibly resulting in haemothorax.
