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

An elderly patient with an extensive smoking history presented with acute severe right-hand pain and evolving weakness with patchy sensory deficit. He had minimal relief from multiple analgesics, gabapentin, and acupuncture. Motor deficits in his right-hand progressed. A nerve conduction study confirmed motor-predominant polyneuropathy and magnetic resonance imaging (MRI) of his C-spine and brachial plexus ruled out apical lung mass or other structural lesions. A positive GalNAc-GD1a ganglioside antibody (IgG) was noted. A diagnosis of immune mediated neuralgic amyotrophy or Parsonage-Turner Syndrome was made. Intravenous immune globulin (IVIG) was started with partial improvement in motor function, six months later. Although this patient did not have SARS-CoV-2 infection nor was he recently vaccinated, this case is of interest to hospital-based internists as the Covid pandemic has seen an increase in the in reported cases of neuralgic amyotrophy worldwide due to the virus itself as well as the associated COVID-19 vaccines.
