Atypical language lateralization and contralateral epileptiform activity in a right-handed patient with a left frontal cortical lesion: A multimodal presurgical evaluation.
Article in Surgical neurology international, 2026. 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
Background: Adult-onset epilepsy due to intracranial focal lesions in one hemisphere mostly results in language function lateralization to the contralateral hemisphere. However, cortical reorganization in certain cases has led to atypical lateralization patterns. In view of this variability, comprehensive presurgical diagnostics and planning have proven to be essential in preventing postoperative complications. Case Description: We report a clinically significant case of a right-handed 40-year-old male presenting with new-onset focal epilepsy secondary to a small, nonenhancing expansile lesion in the left middle frontal gyrus. Multimodal presurgical workup revealed atypical right hemisphere language dominance and interictal epileptiform discharges over the contralateral right temporal region, raising unique considerations for surgical planning. Conclusion: This case highlights the value of integrated functional magnetic resonance imaging and electroencephalography assessment in epilepsy surgery, especially in the context of cortical reorganization.
