1 · What the graph read from it

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.

2 · The registry

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: Premature rupture of membranes (PROM) is defined as the leakage of amniotic fluid before the onset of labor and delivery contractions. Some studies found that women who experienced PROM had significantly lower vitamin C blood levels than those who did not, while others found no significant differences. Previous systematic reviews and meta-analyses on the efficacy of vitamin C in the prevention of PROM had conflicting results. Aims: Conduct a systematic review and meta-analysis to determine if there was a significant difference in vitamin C blood levels in women who had PROM versus the control group who did not and to determine if vitamin C supplements could help prevent it. Study Design: Systematic review and meta-analysis. Methods: We registered our protocol with PROSPERO (CRD42022371644). We searched PubMed/MEDLINE, Web of Science, and Scopus through February 15, 2024. Additionally, backward and forward citation searches were conducted. Studies were selected based on predetermined inclusion and exclusion criteria. Meta-Essentials: Workbooks for Meta-Analysis (version 1.5) was used for analysis. Results: Twenty-five studies (26 reports) met all eligibility criteria, with 18 studies (18 reports) assessing vitamin C levels and seven studies (eight reports) evaluating efficacy. Women with PROM, whether preterm or term, had significantly lower vitamin C levels [Hedges’ g, -1.48; 95% confidence interval (CI): -2.82, -0.14; Conclusion: Women with PROM, particularly those who developed it preterm, appear to have significantly lower vitamin C levels, and vitamin C supplementation appears to be effective in reducing the risk of PROM, particularly preterm PROM. More high-quality studies with low risk of bias, more homogenous, and larger samples are needed to confirm these findings.
