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

objectiveThis study aimed to assess hippocampal microstructural alterations in patients diagnosed with temporal lobe epilepsy with hippocampal sclerosis (TLE-HS) and to evaluate the diagnostic utility of diffusion kurtosis imaging (DKI) in this population.

methodsA total of 53 patients with TLE-HS and 53 healthy controls (HC) underwent brain magnetic resonance imaging, including standard sequences and DKI acquisition. Bilateral hippocampi were defined as regions of interest. DKI-derived parameters and the FLAIR signal intensity ratio (R

resultsThe hippocampus on the affected side in patients with TLE-HS demonstrated significantly increased mean diffusivity, axial diffusivity, and radial diffusivity, along with significantly decreased axial kurtosis (AK), mean kurtosis (MK), and radial kurtosis, when compared with both the unaffected hippocampus and the hippocampi of the HC group (all p < 0.05). No significant differences in fractional anisotropy (FA) values were observed between the affected hippocampus and either the unaffected side or the HC group (p > 0.05); however, FA values in the unaffected hippocampus differed significantly from those in of the HC group (p < 0.05). In TLE patients, the lateralization index of DKI parameters and R

conclusionDKI-derived metrics provided sensitive indicators of hippocampal microstructural disruption in unilateral TLE-HS. These findings support the potential of DKI as a valuable adjunctive tool in the evaluation of hippocampal integrity in TLE-HS.
