A systematic review on the effects of maternal calcium supplementation on offspring's blood pressure.
Review in Journal of research in medical sciences : the official journal of Isfahan University of Medical Sciences, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 2 of them syntheses 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
backgroundEvidence proposes that maternal calcium (Ca) supplement during pregnancy may be inversely associated with the off spring's blood pressure (BP) level. It is suggested that increased maternal Ca intake during pregnancy may result in lower BP in the off spring. The reduction in the incidence of hypertension in mothers is documented but the effects on the off spring are uncertain. MATERIALS AND
methodsWe conducted a systematic review of the literature to summarize the evidence supporting an association between maternal dietary Ca intake during pregnancy and the BP in the off spring. In this systematic review, relevant papers were selected in three phases. After quality assessment, a reviewer extracted the data while the other one checked the extracted data. We summarized the information regarding the association of maternal Ca intake either by food or supplements with BP in the off spring.
resultsFour randomized trials and three observational studies were included in this review. The results were more consistent among the studies including older children (1-9 years) where a higher maternal Ca intake was associated with a reduction in the off spring's systolic BP. One large randomized trial found a clinically and statistically significant reduction in the incidence of elevated BP in 7-year-old children [relative risk (RR) = 0.59, 95% confidence interval (CI) 0.39-0.90].
conclusionOverall, our findings confirm the beneficial effects of maternal Ca intake during pregnancy for the off spring's BP level.
