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
introductionOxidative stress (OS) is implicated in dementia. While elevated peripheral OS biomarkers were observed in vascular mild cognitive impairment (vMCI), the role of central antioxidants remains unclear. We assessed levels of the major brain antioxidant glutathione (GSH) in vMCI compared to cognitively normal coronary artery disease (CAD) controls (CN).
methodsIn vivo tissue-corrected GSH in the anterior cingulate cortex (ACC) and occipital cortex (OC) were quantified in persons with vMCI and CN using MEscher-GArwood Point RESolved magnetic resonance Spectroscopy.
resultsAmong participants (vMCI, n = 22, age [mean ± SD] = 67.4 ± 7.3; CN, n = 21, age = 66.7 ± 7.8), ACC-GSH (i.u. ± SD) was higher in vMCI (4.42 ± 0.59) versus CN (3.72 ± 1.01) (Z = -2.5, p = .01), even after controlling for age and sex (B [SE] = 0.74 [0.26], p = .007). Increased ACC-GSH correlated with poorer executive function (EF) (B [SE] = -0.31 [0.14], p = .04). OC-GSH showed no effect. DISCUSSION: Higher ACC-GSH in vMCI may reflect a compensatory response to OS. ACC-GSH was negatively correlated with EF, suggesting a linkage between regional brain antioxidants and disease-relevant cognitive domains. HIGHLIGHTS: Brain GSH was measured in vascular MCI and matched controls using MEGA-PRESS. In contrast to GSH deficits in AD, anterior cingulate GSH was elevated in vMCI. Brain GSH was correlated with disease-relevant cognitive domains in vMCI. The GSH antioxidant system may be etiologically implicated in vMCI.
