Article in Current pharmaceutical design, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionThis research aimed to reveal the role of antioxidants and DNMT1 gene expression in behavioral disorders after exposure to stress.
methodsForty-eight male and female mice (weight 25-35 grams) were used. Their pups (weight 18-22 grams) were divided into 6 groups (n=20), Control, Social isolation stress (SIS), and SIS + N-acetylcysteine (NAC) 150 mg/kg intraperitoneally for male and 3 similar groups for female subjects, eight mice from each group were used for the first-generation experiments and another for mating and producing the second generation. The second-generation pups were designated into 9 groups A to I. After conducting behavioral tests of the Morris water maze (MWM) and shuttle box, they were anesthetized, decapitated, and their brains were removed. The neuronal counts of CA1 and CA3 were performed. DNMT1 gene expression, total antioxidant capacity (TAC), and malondialdehyde (MDA) of the brain were measured.
resultsSpatial memory, passive avoidance, and TAC decreased in the SIS groups. MDA and DNMT1 gene expression of the SIS groups increased (p<0.001). Dead neurons in the CA1 and CA3 regions increased in the SIS group (p<0.001). DISCUSSION: According to the results of this study, N-acetylcysteine enhanced learning and memory while reducing neuronal death by decreasing oxidative stress. Additionally, it lowered the expression of the DNMT1 gene, which plays a crucial role in DNA methylation.
conclusionAfter studying the human population, N-acetylcysteine may be introduced as an adjunct therapy to help mitigate the effects of stress.
