High-dose intravenous vitamin C reduce C-reactive protein levels, fluid retention, and APACHE II scores in patients with moderately severe acute pancreatitis: a prospective, randomized, double-blinded, placebo-controlled study.

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
backgroundThe aim of this study was to investigate whether high-dose intravenous vitamin C (HDIVC) could decrease the mortality rate within 28 days among patients moderately severe acute pancreatitis (MSAP) and severe acute pancreatitis (SAP).
methodsIn this randomized, placebo-controlled trial, patients diagnosed with predicted MSAP or SAP within 72 h of symptom onset were enrolled to receive either a vitamin C infusion (200 mg/kg/24 h) or a matched placebo for 7 days. The primary outcome was 28-day mortality.
results212 adults including 155 MSAP and 57 SAP were enrolled from September 2019 to June 2023. The trial was terminated prematurely due to a lower than expected 28-day mortality rate which showed no difference between the HDIVC and Control group (3/109 vs. 4/103, unadjusted OR: 0.70, 95% CI, 0.15-3.21, p = 0.647). Among patients with MSAP, the HDIVC group exhibited a more pronounced reduction in C-reactive protein levels compared to the Control group (Day0 to Day3, median 72 mg/L vs. 46 mg/L, p = 0.003; Day0 to Day7, median 168 mg/L vs. 121 mg/L, p = 0.013); The volume of fluid retention was lower in the HDIVC group compared to the Control group (Day0-Day1, median 676.5 ml vs. 1130 ml, P = 0.04; Day0-Day2, median 511 ml vs. 1290 ml, P = 0.02; Day0-Day3, median 692 ml vs. 1534 ml, P = 0.04). The APACHE II scores reduction from Day0 to Day7 was significantly greater in the HDIVC group in APACHE II scores (median change of 3 vs. 2, P = 0.01). No significant difference was observed among patients with SAP.
conclusionHDIVC did not significantly reduce 28-day mortality in MSAP and SAP patients. While it showed potential benefits in reducing CRP, fluid retention, and APACHE II scores in MSAP patients, these effects may not be directly related to the study drug, and no similar changes were observed in SAP patients.
