Dorsal Interosseous Muscle Weakness from Mid-palm Ganglion Cyst.

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
Ulnar nerve compression is commonly seen at the elbow at the cubital tunnel and the wrist at the Guyon canal but is rarely seen in the hand. This case report describes an 18-year-old male presenting with seven months of atraumatic hand weakness and atrophy associated with heavy weightlifting. Exam demonstrated isolated interosseous muscle atrophy mostly sparing the abductor digiti minimi with intact sensation and negative nerve compression tests including Tinel at carpal and ulnar tunnels, Froment sign, Wartenberg test, cross finger test, and Spurling test. Electromyography and nerve conduction studies demonstrated prolonged distal latency, low amplitude potential, and large amplitude fibrillations with severely reduced motor unit firing in the first dorsal interosseous muscle consistent with ulnar nerve deep motor branch compromise. Magnetic resonance imaging revealed a ganglion cyst between the third metacarpal shaft and the flexor profundus tendon. Given the progressive symptoms, ganglion cyst excision and ulnar motor nerve branch neurolysis were performed.
