Ultrasound-Detected Ulnar Nerve Entrapment With Normal Electrodiagnostic Studies Following Thoracic Outlet Decompression: A Case Report.
Article in Cureus, 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
We report the case of a 38-year-old female who developed persistent right upper extremity paresthesia, neuropathic pain, and ulnar-sided sensory disturbance following surgical decompression for thoracic outlet syndrome (TOS). Despite clinically significant cubital tunnel tenderness and ultrasound evidence of focal ulnar nerve impingement, electrodiagnostic studies, including nerve conduction studies (NCS) and electromyography (EMG), were normal. The patient underwent ultrasound-guided ulnar nerve hydrodissection with corticosteroid and dextrose solution as part of conservative management. This case underscores that cubital tunnel syndrome should not be excluded solely on the basis of normal electrodiagnostic studies, particularly when clinical and imaging findings are suggestive.
