Ulnar Neuropathy Caused by a Giant Epidermal Cyst at the Elbow: Case Report.
Article in NMC case report journal, 2024. 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
Here, we report an unusual case of ulnar neuropathy at the elbow caused by a giant epidermal cyst. A 76-year-old man was assessed on an outpatient basis for ulnar numbness of the left hand that had persisted for 6 months. A soft, elastic subcutaneous mass 6 cm in size was noted on his left elbow. He felt numbness on the ulnar aspect of the left fourth and fifth fingers, corresponding to the area innervated by the ulnar nerve, which worsened upon elbow flexion. An electrophysiological study revealed ulnar neuropathy at the elbow. To remove the subcutaneous mass at the left elbow and open up the ulnar tunnel, surgery was performed. There were no signs of nerve impingement or a neuroma on the ulnar nerve. The histological diagnosis was an epidermal cyst. On the day after surgery, numbness on the ulnar aspect of the left hand upon elbow flexion was markedly abated.
