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

Gephyrin is a postsynaptic scaffold protein essential for inhibitory neurotransmission. Gephyrin-immunoglobulin G (IgG) was reported, decades ago, in a single case of paraneoplastic stiff-person-like syndrome, but its broader clinical relevance remains unknown. While investigating unclassified synaptic IgGs mimicking amphiphysin-IgG, we identified gephyrin-IgG in 3 patients using human protein microarray. Gephyrin specificity was confirmed using confocal tissue-based immunofluorescence assay, cell-based assay, and Western blot. The 3 patients, all female, had: encephalitis (2) and myeloneuropathy and breast cancer (1). All had inflammatory cerebrospinal fluid and abnormal magnetic resonance imaging, and improved following immunotherapy. Gephyrin-IgG is associated with a treatable autoimmune neurological disease, sometimes paraneoplastic.
