Shedding light on gestational loss: The role of Vitamin D 25(OH)D deficiency in miscarriage - A systematic review and meta-analysis.
Article in Tzu chi medical journal. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objectives: Miscarriage is a common pregnancy complication with various contributing factors. Recent studies suggest that maternal Vitamin D deficiency may increase the risk of early pregnancy loss. Vitamin D is essential for immune regulation, placental development, and fetal growth. This meta-analysis aimed to evaluate the association between maternal Vitamin D status and miscarriage. Materials and Methods: This meta-analysis followed PRISMA 2020 guidelines, including observational studies from PubMed, EMBASE, Scopus, Web of Science, and Cochrane (2018-2025). Eligible studies reported serum 25(OH)D levels and miscarriage outcomes. Data on serum Vitamin D, miscarriage incidence, and odds ratios (ORs) were extracted. Study quality was assessed using the Newcastle-Ottawa Scale. Statistical analyses were performed using Review Manager 5.4 and R, with evaluation of heterogeneity and publication bias. Results: Women who experienced miscarriage had significantly lower Vitamin D levels than those with ongoing pregnancies (mean difference: -5.48 ng/mL; 95% confidence interval [CI]: -9.77 to -1.19; Conclusion: Maternal Vitamin D deficiency is significantly associated with an increased risk of miscarriage. These findings support the potential benefit of assessing and optimizing Vitamin D status in preconception and antenatal care to improve the pregnancy outcomes.
