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

backgroundPeripherally induced movement disorders represent a rare and debated complication of peripheral trauma. It is difficult to determine a causal relationship between peripheral injuries and subsequent movement disorders. CASES: Here, we introduce and characterize four patients with post-surgical scar-associated movement disorders, a peripherally-induced rippling movement disorder confined to the muscles just under a long surgical incision scar, appearing weeks to months after surgery. This novel 'scar dancing' syndrome does not spread to adjacent muscles and persists during sleep.

conclusionScar dancing syndrome expands the phenotypic spectrum of peripherally induced movement disorders, in which movement disorder is confined to a long surgical incision site.
