Superficial and deep white matter abnormalities in temporal lobe epilepsy.
Article in Brain communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Non-invasive neuroimaging is important in epilepsy to help identify cerebral abnormalities. Abnormally reduced fractional anisotropy (FA) in deep white matter (WM) from diffusion-weighted imaging (DWI) is widely reported in large multi-cohort studies across all types of epilepsies. However, abnormalities in FA for superficial WM are rarely investigated in epilepsy. To gain a greater understanding of the nature of WM abnormality at different WM depths, we investigated DWI abnormalities at a range of superficial and deep WM in two separate temporal lobe epilepsy (TLE) cohorts. The first cohort (TLE = 81, Healthy Control; HC = 67) underwent a high angular resolution multi-shell DWI, whilst the second cohort (TLE = 70, HC = 29) had a single-shell acquisition. We registered FA maps to a standard template, and analysed temporal WM within 8 mm of the temporal lobe grey matter, amygdala and hippocampus. We standardised FA measures at different depths, and compared ipsi-versus contralateral temporal WM, and MRI-positive versus MRI-negative groups. We report three major findings: First, superficial WM had greater FA reductions than deep WM in TLE (
