A rare axillary artery branching variation: case report in a Brazilian cadaver.
Article in Jornal vascular brasileiro, 2025. 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
Knowledge of vascularization is essential for surgical planning and interventional procedures in the axillary region. The axillary artery gives off branches supplying the shoulder, thoracic wall, and scapula. It then continues as the brachial artery, which furnishes branches to the arm and elbow. Minor variations in these branches are common. However, dissection of a formalin-fixed right upper limb revealed an axillary artery that bifurcated into a superficial brachial artery, which did not give off any branches, and a posterior trunk, that gave rise to all the branches typically originating from the third part of the axillary artery and the brachial artery, including the subscapular artery, the humeral circumflex arteries, the deep brachial artery, and the collateral ulnar arteries. This rare vascular arrangement has not been previously described in Brazil. Awareness of these variations may prevent diagnostic errors and injuries during surgeries.
