Ictal cold shiver caused by autoimmune limbic encephalitis: A case report and literature review.
Article in Epilepsy & behavior reports, 2025. 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
Ictal cold shiver is a rare manifestation of seizures that originate in the temporal lobes; it is characterized by body trembling and sensations of cold. This study aims to investigate the clinical manifestations and etiological factors in patients with ictal cold shiver. We reviewed 59 cases of ictal cold shiver by using various keywords to search published original articles and case reports, and we described a new case of autoimmune limbic encephalitis. The median age at diagnosis was higher in patients with autoimmune encephalitis than in those with other etiologies (p = 0.007). Autoimmune encephalitis showed more frequent bilateral temporal lobe abnormalities on magnetic resonance imaging (MRI) (p = 0.027) and generalized or bilateral independent epileptiform discharges on electroencephalography (EEG) (p = 0.047). Anti-leucine-rich glioma-inactivated 1 antibodies were most commonly detected in patients with autoimmune encephalitis with ictal cold shiver (85.7 %). This study highlights the importance of considering autoimmune mechanisms in the presence of ictal cold shiver, especially in patients with bilateral temporal lobe lesions on MRI, generalized or bilateral independent epileptiform discharges on EEG, and older onset.
