Noise pollution during pregnancy and congenital issues: systematic review and meta-analysis.
Synthesis in BMC pregnancy and childbirth, 2026. 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
backgroundThis study provides a systematic review of the literature on the association between noise pollution during pregnancy and congenital malformations, including neural tube defects, orofacial clefts, cardiac defects, and hearing dysfunction. MATERIALS AND
methodsThe search used the keywords "noise pollution during pregnancy" and "congenital issues." Two independent investigators extracted studies from Web of Science, Medline (PubMed), Embase, and Scopus through July 2024. After removing duplicates, a systematic review of 11 studies and a meta-analysis of 9 studies were conducted, involving 1,522,346 participants. The review followed PRISMA guidelines and utilized the JBI critical appraisal checklist. Data were extracted in Excel and analyzed using STATA 17.
resultsNoise pollution during pregnancy was significantly associated with congenital anomalies (OR = 1.68, 95% CI: 1.25-2.27, I² = 69.77%). However, no significant association was established between noise pollution and heart defects (OR = 1.48, 95% CI : 0.97-2.15).
conclusionsThis study concludes that women exposed to noise pollution during pregnancy are at an increased risk of congenital anomalies, emphasizing the need for further research on its effects on pregnancy outcomes.
