Intravenous vitamin C as micronutrient therapy in patients with sepsis or septic shock: an updated systematic review and meta-analysis of randomized controlled trials.

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
Objective: The adjunctive therapeutic value of vitamin C in sepsis or septic shock patients remains controversial. This study aimed to evaluate the therapeutic efficacy and safety of intravenous administration of vitamin C in sepsis or septic shock patients through meta-analysis. Methods: Relevant literature was searched in PubMed, Embase, and Scopus databases and other related databases. The primary outcome was 28-day mortality. Secondary outcomes included duration and total dose of vasopressors, change in sequential organ failure assessment (SOFA) scores from baseline to the earliest reported time point between 72 and 96 h (ΔSOFA), hospital length of stay, intensive care unit length of stay, urine output in the 24-h, and incidence of adverse events. Results: Fourteen randomized controlled trials enrolling 1,958 patients were eligible for assessment. Meta-analysis demonstrated that intravenous vitamin C reduced 28-day mortality in sepsis or septic shock patients compared to the control group (RR 0.70; 95% CI 0.53 to 0.93; Conclusion: This meta-analysis suggests that intravenous vitamin C might be associated with reduced mortality in sepsis, but the benefit was not confirmed in low-risk-of-bias multicenter trials and was primarily driven by single-center studies. Intravenous vitamin C appeared safe. Given the exploratory nature of these subgroup analyses and the data-driven thresholds used, high-quality, multicenter RCTs are warranted.
