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

A 34-year-old woman with drug-resistant epilepsy underwent simultaneous scalp and stereo-EEG (sEEG) and had seven seizures, three of them without visibility on the scalp EEG. Of the four seizures seen on both sEEG and scalp EEG, the seizure onset in the scalp EEG was ipsilateral to the seizure onset in the sEEG in two seizures and contralateral to the sEEG onset in two seizures. This unusual lateralization discordance of scalp EEG and sEEG highlights the importance of bilateral lead placement in stereo EEG to accurately identify the seizure onset zone.
