Brain glutathione levels and associations with recent drinking in treatment-naïve individuals with alcohol use disorder versus light drinkers.
Article in Drug and alcohol dependence, 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
BACKGROUND AND
aimsRepeated ethanol exposure produces excess oxidative stress resulting in cellular damage, with glutathione (GSH), the brain's primary antioxidant, conferring a critical first line of defense. This study aimed to compare brain GSH levels between treatment-naïve individuals with Alcohol Use Disorder (AUD) and light drinking control participants (LD). This study also aimed to evaluate associations of brain GSH levels with recent heavy drinking in AUD and LD participants. DESIGN SETTING AND
participantsSecondary analyses were conducted on cross-sectional neuroimaging data from (n = 20) treatment-naïve individuals with AUD and (n = 20) demographically matched LD participants at a medical university in South Carolina, USA. MEASUREMENTS: CSF-corrected and water-referenced GSH levels from dorsal anterior cingulate cortex (dACC) acquired via proton MR spectroscopy and past 14-day number of heavy drinking days (nHDD) acquired via Time-Line Followback interview.
findingsSignificantly higher dACC GSH/water levels were observed in AUD participants (M = 0.88, SD = 0.16) than in LD participants (M = 0.70, SD = 0.16, F = 12.00, p < 0.001; Cohen's d = 1.10). Additionally, there was a significant interaction between GSH/water levels and participant group (F = 5.71, p = 0.022), such that higher GSH/water levels were associated with lower nHDD in AUD (r = -0.46, p = 0.040) but not LD (r = 0.24, p = 0.329) participants.
conclusionsThe findings from this preliminary study are consistent with an interpretation of compensatory GSH upregulation in response to moderate oxidative stress in treatment-naïve individuals with AUD, adding unique support to oxidative stress models of alcohol-related cellular damage and highlighting the potential promise of antioxidant treatments for AUD.
