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

backgroundPiloerection, a physiological response to cold or emotional stimuli, is a rare autonomic manifestation of epileptic seizures. The anatomical correlates and electrophysiological mechanisms of pilomotor seizures remain poorly understood.

methodsWe conducted a retrospective analysis of 13 patients with pilomotor seizures identified from 8482 individuals monitored at the Epilepsy Center of West China Hospital. Demographics, seizure characteristics, neuroimaging, and neurophysiological findings were analyzed to determine the epileptogenic zones and associated etiologies.

resultsMost (11/13) of our cases showed temporal lobe origin of seizures, with distinctive ictal encephalogram patterns including rhythmic delta activity. Piloerection was consistently accompanied by other autonomic or psychic symptoms. Most patients responded to anti-seizure medications.

conclusionsPilomotor seizures are associated with temporal lobe epilepsy and are frequently associated with specific etiologies such as autoimmune encephalitis.
