Hydrogen gas inhalation therapy may not work sufficiently to mitigate oxidative stress induced with REBOA.
Article in Scientific reports, 2024. 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
Hemorrhagic shock is a significant cause of trauma-related mortality. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a less-invasive aortic occlusion maneuver for severe hemorrhagic shock but potentially inducing oxidative stress injuries. In an animal model, this study investigated hydrogen gas inhalation therapy's potential to mitigate post-REBOA ischemia-reperfusion injuries (IRIs). Ten healthy female swine underwent REBOA placement after induced 40% hemorrhagic shock. They were observed during the IRI phase after a 60-minute Zone 1 occlusion for 180 minutes until euthanasia. 2% hydrogen gas inhalation was started simultaneously with REBOA inflation in the hydrogen group. We evaluated survival time, lactate, and 8-hydroxy-2'-deoxyguanosine (8-OHdG) biomarkers, gross findings, and pathological grades. One swine in the control group died at 90 min, and the remaining animals survived throughout the experiment. Survival analysis showed no significant differences between the two groups (control vs. hydrogen, 4/5 vs. 5/5; Log-rank, P = 0.317). Lactate levels during and after REBOA suggested a tendency towards lower levels in the hydrogen group (10.5 ± 4.2 vs. 7.6 ± 2.3 mmol/L, peak, T = 90). Serum 8-OHdG concentrations showed a lower trend in the hydrogen group (Range: 0.12-0.32 vs. 0.11-0.19 ng/mL). The villi of the ileum were destroyed during REBOA inflation and after reperfusion. Changes in the pathological grade of the ileum demonstrated no significant differences in both groups (2.8 ± 1.0 vs. 2.0 ± 1.0, proximal ileum, T = 240). Hydrogen gas inhalation therapy exhibited no significant difference compared to the control group in survival, lactate level, 8-OHdG, and intestinal mucosal injury following REBOA in a hemorrhagic shock model. Although it may slightly reduce mortality, biomarkers, and intestinal pathology, hydrogen gas inhalation therapy was not shown to have sufficient evidence to mitigate REBOA-IRI.
