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

A 56-year-old man with a remote history of bilateral recurrent facial palsies presented with a week of ophthalmoplegia with intact deep tendon reflexes and lack of ataxia, cerebrospinal fluid with albuminocytologic dissociation and elevated serum anti-ganglioside Q1b (GQ1b) IgG antibody. We diagnosed the patient with acute ophthalmoplegia without ataxia, a condition under the spectrum of anti-GQ1b antibody syndromes which also includes Miller Fisher syndrome. Given the rarity of recurrent facial palsies and anti-GQ1b antibody syndromes as well as reports associating facial palsies and this syndrome, we suggest that our case may be an unusual presentation of an anti-GQ1b antibody syndrome beginning with recurrent facial palsies several years prior to ophthalmoplegia. Prior studies of human nerves provide insight into the pathophysiology, including ganglioside distribution and cross-reactivities underlying the heterogeneity of anti-GQ1b antibody syndromes. This report may expand the differential diagnosis in patients with recurrent facial palsies and broaden the phenotype of anti-GQ1b syndromes.
