Association of celiac disease with menstrual and hormonal disturbances: a systematic review and meta-analysis.
Synthesis in Reproductive biology and endocrinology : RB&E, 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
backgroundDisturbances in the female reproductive system are known extraintestinal manifestations of celiac disease (CD). However, the reliability of the existing literature is limited by small study populations and heterogeneous study designs. This study is the first systematic review and meta-analysis to synthesize all available evidence and provide a comprehensive evaluation of the association between CD and female menstrual and hormonal parameters.
methodsA systematic literature search was conducted in PubMed, Scopus, and Cochrane Central databases using keywords related to CD, menstrual characteristics, and hormonal markers. Studies published until August 2025 were included.
resultsOur analysis demonstrated a significantly higher mean age at menarche in girls with CD compared with controls [pooled mean difference (MD): 0.64 years, 95% confidence interval (CI): 0.32 to 0.95, p = 0.0007), as well as an increased risk of abnormal uterine bleeding [pooled odds ratio (OR): 2.11, 95% CI: 1.23 to 3.63, p < 0.05] and amenorrhea (pooled OR: 4.03, 95% CI: 1.11 to 14.65, p = 0.0394). Menopausal age was not found to be earlier in women with CD (pooled MD: -1.31 years, 95% CI: -3.02 to 0.40, p = 0.1053). Adherence to a gluten-free diet was not associated with age at menarche when adherent and non-adherent patients were compared (pooled MD: 0.56 years, 95% CI: -0.72 to 1.83, p = 0.260). Furthermore, none of the evaluated biochemical hormonal markers (FSH, LH, estradiol, prolactin, and AMH) differed significantly between women with CD and controls.
conclusionThis systematic review and meta-analysis reinforces the existing evidence that CD may adversely affect several aspects of menstrual health in women without significantly impacting biochemical hormonal markers.
