A multimodal epilepsy dataset of paired 3-Tesla and 7-Tesla MRI and intracranial EEG.
Article in Scientific data, 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
There is an increasing need to integrate multimodal datasets in epilepsy research, particularly to correlate electrophysiology with imaging in patients with refractory epilepsy. We present a multimodal paired 3T and 7T MRI dataset acquired from 30 drug-resistant focal epilepsy patients (18 females, 38.8 ± 11.7 years) who underwent T1-weighted (T1w), T2-weighted (T2w), Fluid Attenuated Inversion Recovery (FLAIR), and resting-state functional MRI (rs-fMRI). In addition to the raw data, we release preprocessed anatomical and functional data, along with various quality control and clinical metadata files. For participants who subsequently underwent intracranial EEG (iEEG) (n = 15), curated ictal and interictal epochs are also included. We demonstrate a potential application of this paired 3T and 7T data by training a deep learning model capable of synthesizing high-field 7T T1w MR images from the 3T equivalents. We anticipate that this dataset will facilitate future multiscale analyses in epilepsy.
