Probiotic supplementation and postoperative antioxidant response in patients undergoing open‑heart surgery: a randomized controlled trial.

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: Oxidative stress is a major contributor to postoperative complications in patients undergoing open-heart surgery. Probiotics have been suggested to enhance antioxidant defenses by modulating gut microbiota and reducing systemic inflammation. This study aimed to evaluate the impact of probiotic supplementation on oxidative stress biomarkers in patients undergoing open‑heart surgery. Methods: A total of 37 patients with cardiovascular disease scheduled for open‑heart surgery were initially recruited, with 18 allocated to the intervention group and 19 to the control group. The intervention, consisting of probiotic supplementation, began 1 day before surgery and continued for 2 weeks, while the control group received a placebo for the same duration. Plasma levels of malondialdehyde (MDA) and total antioxidant capacity (TAC) were measured at baseline and at the end of the intervention using ELISA and colorimetric methods, respectively. Results: The intervention group had a significant increase in TAC levels from 221.52 ± 24.68 to 356.23 ± 34.57, whereas the control group experienced a decrease from 220.73 ± 14.12 to 209.68 ± 14.83 ( Conclusion: Probiotic supplementation may improve the postoperative antioxidant status in patients undergoing open-heart surgery. Probiotics may serve as an adjunctive therapy to enhance antioxidant defenses and mitigate postoperative oxidative stress. Further large-scale studies are warranted.
