In vivo GABA detection by single-pulse editing with one shot.
Article in Magnetic resonance in medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeTwo-shot γ-aminobutyric acid (GABA) difference editing techniques have been used widely to detect the GABA H4 resonance at 3.01 ppm. Here, we introduce a single-shot method for detecting the full GABA H2 resonance signal, which avoids contamination from the coedited M
methodsDensity matrix simulation was conducted to optimize the pulse-sequence timing, aiming to reduce the interfering glutamate H4 signal and minimize the correlation between glutamate and GABA arising from spectral overlap. The optimized sequence was used to acquire MR spectroscopy data from a 14-mL voxel in the anterior cingulate cortex of 6 healthy participants.
resultsThe GABA H2 peak was consistently observed in all participants. The GABA/creatine ratios in the participants were determined to be 0.07 ± 0.01 with Cramer-Rao lower bounds of 8.0% ± 2.2%. Spectra acquired following [U-
conclusionThe proposed single-shot GABA editing method effectively minimizes interference from the glutamate H4 signal in the detection of the full GABA H2 signal, which resonates at a spectral region with much reduced macromolecule contamination.
