High-Resolution Mapping of Tumor and Peritumoral Glutamate and Glutamine in Gliomas Using 7-T MRSI.
Article in Radiology. Imaging cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Purpose To evaluate glutamate (Glu) and glutamine (Gln) concentrations in patients with glioma using 7-T MR spectroscopic imaging, identify significant differences in metabolic ratios between tumor and peritumoral regions, and assess associations of Glu and Gln with tumor-associated epilepsy and other tumor characteristics. Materials and Methods This retrospective study included data from patients with gliomas who underwent 7-T MR spectroscopic imaging in a single university hospital between September 2018 and April 2021. Median values for nine metabolic ratios were calculated within the visible tumor and peritumoral shell, and Dice similarity coefficients were used to assess the spatial overlap of elevated metabolic regions between these compartments. Statistical significance between regions of interest and between glioma attributes (eg, isocitrate dehydrogenase status) was assessed. Results Thirty-six patients (median age, 52 years [IQR, 23 years]; 22 male, 14 female) were included in the study. The Glu to total creatine (Glu/tCr) median was significantly higher in the peritumoral volume of interest (median, 1.13) compared with the tumor (median, 0.92;
