Maternal Calcium Intake at 36 Weeks' Gestation and Pre-Eclampsia Risk-A Cohort Study.
Article in BJOG : an international journal of obstetrics and gynaecology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
objectiveThe objective of this study is to examine the association between dietary calcium intake (Ca) and pre-eclampsia (PE).
designCohort study.
settingInner-city hospital. POPULATION: A total of 2838 women with singleton pregnancies at 35
methodsOnline 24-h dietary recall questionnaire was used to measure Ca intake. In the low (< 700 mg/d) vs. adequate (≥ 700 mg/d) Ca intake groups, we compared the prevalence of PE-associated maternal risk factors and the incidence of PE. In multivariate regression, we examined the low Ca intake and PE relationship, adjusted for established PE risk factors (including blood pressure and angiogenic biomarkers) and any additional factors associated with low Ca intake specifically.
main outcome measurePE.
resultsOverall, 405 (14.3%) women had low Ca intake. Low (vs. adequate) Ca intake was associated with a higher incidence of PE (6.2% vs. 2.9%; odds ratio 2.2, 95% confidence interval 1.3-3.7), as well as more prevalent risk factors for PE, including Black ethnicity (34.1% vs. 11.8%), South Asian ethnicity (10.1% vs. 7.2%), high body mass index (29.8 vs. 28.3 kg/m
conclusionsAlthough some contribution from low Ca to the development of PE cannot be ruled out, after accounting for maternal characteristics, medical history and deprivation, low Ca intake did not make an independent contribution to the development of PE in this population of mixed-ethnicity women.
