1 · What the graph read from it

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.

2 · The registry

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

Carpal tunnel syndrome (CTS) is the most common peripheral entrapment neuropathy. While most cases are idiopathic, secondary CTS due to space-occupying lesions such as tumors is relatively uncommon. We report a rare case of simultaneous compression of the median nerve and the dorsal cutaneous branch of the ulnar nerve by a small lipoma arising from the flexor tenosynovium. Magnetic resonance imaging clearly demonstrated the lesion within the carpal tunnel and near Guyon's canal. Surgical excision led to resolution of median nerve symptoms, whereas ulnar sensory disturbance persisted due to involvement of the unrecognized dorsal cutaneous branch of the ulnar nerve. The patient later developed cubital tunnel syndrome, and concurrent compression of the dorsal cutaneous branch of the ulnar nerve complicated neurological assessment. This case emphasizes the need for comprehensive assessment and early MRI evaluation in atypical or unilateral CTS.
