A randomized trial of ascorbic acid for the prevention of post-reperfusion syndrome during liver transplantation.

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
backgroundPost-reperfusion syndrome (PRS) is a critical hemodynamic complication during liver transplantation, characterized by a significant drop in mean arterial pressure and associated with increased morbidity and mortality, systemic inflammation, and ischemia-reperfusion injury. Ascorbic acid (AA), with its antioxidant and anti-inflammatory properties, has been proposed as a potential therapeutic intervention.
methodsA single-center, double-blind, randomized controlled trial was conducted at the Hospital Universitario Ramón y Cajal, Madrid. Patients undergoing liver transplantation were randomly assigned to receive either 1500 mg of intravenous AA during the anhepatic phase (vitamin C-treated group) or 0.9% saline as a placebo (control group). The primary endpoint was PRS incidence. The secondary outcomes included inflammatory cytokine levels, postoperative renal function, and patient/graft survival.
resultsThirty-nine patients were randomized (20 controls and 19 AA-treated patients). The incidence of PRS was 30% in the control group and 10.5% in the AA group (p=0.235). Postoperative renal failure occurred more frequently in the AA group (68.4%) than in the control group (35%) (p=0.037). Four AA-treated patients (21.1%) required re-transplantation. No significant differences in cytokine levels were observed between the groups, although increases in IL-6, IL-8, and IL-10 levels were noted in patients with PRS, suggesting a stronger inflammatory response.
conclusionsAA supplementation demonstrated a noticeable trend toward reducing PRS during liver transplantation, although this was not statistically significant. An increase in renal failure and the need for re-transplantation were observed in the AA-treated group. Although the study suggests potential benefits, its small sample size limits the conclusions, pointing to the need for larger multicenter trials to determine the optimal dosage and timing.
