Parietal Lobe Epilepsy Associated With 2q13 Duplication: Expanding the Neurogenetic Spectrum.
Article in Cureus, 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
Copy number variations (CNVs) involving the 2q13 region have been associated with a wide range of phenotypes, including developmental delay, dysmorphic features, hypotonia, and congenital heart defects. However, parietal lobe epilepsy has not yet been reported in association with 2q13 duplication. We describe the case of a 20-year-old woman with a duplication of the 2q13 region identified during childhood, who later presented with recurrent, brief episodes of right upper limb paresthesia spreading to other limbs, followed by transient pain. Her past medical history included dyspraxia, polycystic ovary syndrome, atrial fibrillation, and intellectual disability. Electroencephalography (EEG) revealed interictal epileptiform discharges, consisting of paroxysmal sharp theta waves in the left parietal and temporal regions, spreading to adjacent and contralateral areas, particularly during hyperventilation. Based on clinical and EEG features, a diagnosis of parietal lobe epilepsy was established. Treatment with levetiracetam resulted in significant clinical improvement, characterized by complete resolution of the previously described episodes of recurrent, brief right upper limb paresthesia spreading to other limbs, followed by transient pain, as well as a reduction of epileptiform abnormalities on EEG. The duplicated region includes several genes involved in neuronal development, synaptic regulation, and myelination, such as
