Variation of the brachial artery emerging through an opening in the median nerve: a case report.

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
The median nerve maintains a close relationship with the brachial artery in the upper limb. Variability in the formation and distribution of upper extremity vessels is frequently encountered during donor body dissections or surgical procedures. This case presents a rare anatomical variation of the brachial artery emerging through an opening in the median nerve. The median nerve formed a small opening without the contribution from additional nerve roots and the remaining vasculature of the upper limb was otherwise normal. An abnormal arrangement of a neurovascular bundle in the arm can cause sensory and motor issues, as well as vascular implications. This variation has clinical significance in surgical interventions and potentially daily functioning. To our knowledge, this is the first report of a small median nerve opening pierced by the brachial artery.
