The effectiveness of vitamin B6 in reducing mastalgia: a systematic review and meta-analysis.
Synthesis in BMC women's health, 2025. 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
backgroundMastalgia represents the most frequent complaint among women at some point during their lives that can have a profound impact on both the physical and mental well-being of individuals affected by this condition. This study aims to systematically evaluate the effect of vitamin B6 on the severity of mastalgia.
designThis study is a meta-analysis of interventional studies that compare the effects of vitamin B6 to a placebo in healthy women with Mastalgia. The literature search encompassed studies published from inception until November 2024 and was conducted across various electronic databases, including Web of Science, Embase, Cochrane Library, Scopus, PubMed, and Google Scholar, in both English and Persian languages. The severity of breast pain was considered as the outcome measure. Breast pain linked to the menstrual cycle is called cyclic breast pain or cyclic mastalgia. The data were analyzed using Stata software version 17 and a random effects model. The quality of the selected articles was assessed utilizing the Cochrane Risk of Bias assessment checklist.
resultsA total of 301 studies with N = 951 participants (intervention:536, control: 415) were reviewed, with three studies ultimately included in the meta-analysis. The combined analysis of these three studies indicated that there were no differences between the two groups of vitamins B6 and placebo in a reduction of pain intensity (SMD = -3.57, 95% CI: -9.15 to 2.01; very low certainty of evidence), with high heterogeneity among the studies (I² = 99.56%). The overall quality of the included studies was assessed to be low.
conclusionThis meta-analysis did not demonstrate a statistically significant effect of vitamin B6 on mastalgia severity. The evidence is limited by the small number of available studies, low methodological quality, and substantial clinical and statistical heterogeneity. Further well-designed, large-scale randomized controlled trials are needed to reliably determine the efficacy of vitamin B6 for mastalgia. PROSPERO CRD 42,024,613,796.
