Erythrocytic Reduced/Oxidized Glutathione and Serum Thiol/Disulfide Homeostasis in Patients with Opioid Use Disorder.
Article in Psychiatry and clinical psychopharmacology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Background: This study aimed to evaluate oxidative damage by measuring erythrocytic reduced/oxidized glutathione as an intracellular thiol pool and serum thiol/disulfide homeostasis as an extracellular thiol pool in patients with opioid use disorder. Methods: In this prospective cross-sectional study, 33 male patients diagnosed with opioid use disorder and 30 healthy male controls were included. Sociodemographic characteristics and psychometric analyzes were performed and addiction characteristics (duration and amount of heroin use, usage methods) were recorded. For the evaluation of oxidative balance, intracellular reduced-oxidized glutathione (reduced glutathione and oxidized glutathione), and extracellular thiol-disulfide (native thiol and disulfide) levels were measured. Results: There was a decrease in reduced glutathione and native thiol levels and an increase in GSSG and SS levels. Similarly, while oxidized/reduced glutathione, oxidized/total glutathione%, and disulfide/native thiol % ratios increased, the ratio of reduced glutathione/total glutathione% and native thiol/total thiol% decreased. Moreover, a positive correlation was found between the level of both intracellular and extracellular oxidant molecules and the duration and amount of opioid use. Conclusion: Impaired intracellular reduced glutathione/oxidized glutathione and extracellular disulfide/native thiol homeostasis were found in patients with opioid use disorder. The intracellular and extracellular oxidative stress may cause complications related to chronic opioid use.
