Anti-NMDA-receptor encephalitis: an unusual treatable cause of chronic insomnia?
Article in Sleep science (Sao Paulo, Brazil). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
We describe an unusual case of severe and chronic insomnia that proved to be eminently treatable. Initially presumed to be of primary psychiatric/toxicological origin, certain clinical and paraclinical clues led us to the diagnosis of NMDA-receptor encephalitis, an immune-mediated disease of the brain. Our patient responded dramatically to immunotherapy, effectively regaining normal sleep habits and significantly improving his general and mental health after 25 years of insomnia and drug abuse. Immune-mediated encephalopathies should be considered in the differential diagnosis of severe sleep disorders that present with additional neurological signs and symptoms, even when chronic.
