Glutathione Supplementation in Parenteral Nutrition to Prevent Oxidative Stress Related Complications in Preterm Infants: A Narrative Review of Preclinical Efficacy and Safety Profile.
Review in Nutrients, 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
Numerous adverse effects caused by oxidative stress are commonly observed in preterm infants. This stress is caused by the oxidative burden resulting mainly from supplemental oxygen and parenteral nutrition (PN), and by their precarious antioxidant defense. The natural antioxidant defense against these oxidant molecules relies on glutathione, levels of which are low in preterm infants. Given that several short- and long-term biological complications are associated with this oxidative stress, the aim of this narrative review was to discuss glutathione supplementation as a method for reducing it. Consequently, after briefly discussing the effectiveness of partially reducing oxidative stress through adequate photoprotection of PN, it is proposed to correct premature infants' glutathione deficiency by adding glutathione to PN. To justify the proposed intervention, this article will discuss the scientific evidence related to the (1) importance of glutathione, (2) causes of glutathione deficiency and ways to prevent it, (3) reasons why the disulfide form (GSSG) is recommended over the reduced form (GSH) for PN supplementation, (4) efficacy of parenteral GSSG in preventing oxidative stress, and (5) safety profile of glutathione infusion. In conclusion, we believe that the time has come to improve the health of premature infants by providing GSSG-supplemented PN.
