Role of Diffusion Tensor Imaging in Grading of Brain Tumors and Assessment of White Matter Tract Invasion.
Article in Asian journal of neurosurgery, 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
Background: Diffusion tensor imaging (DTI) is a novel advancement of nuclear magnetic resonance that provides an accurate, noninvasive evaluation of brain tumors and their orientation to the adjacent white matter tract. We sought to analyze DTI's role in grading brain tumors and determining white matter tract involvement. Materials and Methods: DTI with the "ep2d_diff_mddw_20_(DTI)" sequence was done in 48 individuals with brain tumors (22 low-grade and 26 high-grade). The DTI measurements, including fractional anisotropy (FA) and apparent diffusion coefficient (ADC), were checked in the tumor itself, the tumor margin, and the area around the tumor. After comparing the results between the two groups, the cutoff was determined using the receiver operating characteristic curve. Tensor maps were obtained by tractography to observe white matter tract involvement. Results: Mean FA values in the intratumoral region and tumor margins were substantially lower in high-grade than low-grade tumors ( Conclusion: DTI is a modern and effective method for predicting tumor aggressiveness and tract involvement in the tumor's surroundings before surgery.
