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

aimsTo summarize the anatomo-electro-clinical characteristics of parietal lobe epilepsy (PLE) subgroups using unsupervised cluster analysis.

methodsThis retrospective cohort study included patients with drug-resistant PLE with seizure freedom after surgery and evaluated scalp video-electroencephalography (EEG) recordings from three epilepsy centers. Hierarchical cluster analysis associated interictal/ictal patterns and initial ictal semiology with anatomical subgroups.

resultsWe analyzed 79 interictal EEG, 141 ictal EEG, and 141 semiological patterns in 47 patients. Cluster analysis associated interictal and ictal discharges from lateral superior parietal lobule epilepsy with centroparietal region distributions on scalp EEG, whereas discharges from other subgroups involved broader regions. Cluster heatmaps of the initial ictal semiology showed: Chapeau de gendarme, affective phenomena, and forced eye deviation in intraparietal sulcus; contralateral limb tonic/clonic or akinetic, affective phenomena, and visual illusions in SPL-lateral; Chapeau de gendarme, behavioral arrest, and vestibular in parieto-occipital sulcus; behavioral arrest in angular gyrus; distal gestural automatisms and cephalic sensations in posterior cingulate; body-perception illusion and contralateral versive in supramarginal gyrus; contralateral facial tonic/clonic in parietal operculum.

conclusionPLE subgroups exhibited distinct scalp EEG features and ictal semiology, reflecting unique propagation networks and highlighting the importance of detailed video-EEG for identifying the epileptogenic zone and guiding intracranial electrode placement.
