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

backgroundPure T1 radiculopathy is very rare. Furthermore, it is difficult to differentiate between C8 radiculopathy and T1 radiculopathy because the C8 and T1 nerve roots are joined at the lower brachial plexus. OBSERVATIONS: The authors report on 2 cases of T1 radiculopathy. Case 1 involved a 47-year-old man with a herniated disc at T1-2 whose symptoms improved after conservative treatment. Case 2 involved a 20-year-old woman with a schwannoma in the T1-2 intervertebral foramen whose symptoms improved after surgical treatment. Both patients presented with numbness, radiating pain, and decreased grip strength in the left upper limb. LESSONS: Weakness of the flexor digitorum profundus (first digit) that is innervated by the median nerve is characteristic of T1 radiculopathy and may be used to differentiate T1 radiculopathy from C8 radiculopathy. https://thejns.org/doi/10.3171/CASE25599.
