Fractal Dimension in Healthy Hippocampi and Hippocampi With Mesial Temporal Sclerosis: An Observational Study.
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
A fractal is a geometric shape that has the same structure across a wide range of scales. The existence of fractal dimension has been demonstrated in various natural structures and translated into a mathematical method through which anatomical structures can be measured with high precision. The hippocampus, located in the mesial area of the temporal lobe, is affected in diseases such as epilepsy, tumors, and viral infections. Mesial temporal sclerosis (MTS) is a condition that significantly degenerates hippocampal neurons and is a major cause of drug-resistant epilepsy. This study aimed to compare the fractal dimension between healthy hippocampi and hippocampi with MTS, and to determine whether there is a difference between them. We analyzed preoperative magnetic resonance imaging (MRI) scans from 12 patients with MTS, calculating the fractal dimension of both the diseased and the contralateral healthy hippocampus using the box-counting method in ImageJ. Healthy hippocampi had a mean fractal dimension of 1.305, while those with MTS had 1.243, representing a 4.75% reduction (p = 0.008). These results suggest that fractal dimension could serve as a quantitative biomarker for hippocampal degeneration in MTS, potentially aiding in earlier diagnosis, guiding treatment strategies, and contributing to research on structural brain changes in epilepsy.
