Efficacy of Vitamin E Supplementation During Pregnancy on the Vitamin E Nutritional Status of the Mother-Child Dyad: A Systematic Review and Meta-Analysis of Randomized Controlled Trial.
Review in Food science & nutrition, 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
The objective of this systematic review and meta-analysis is to investigate the effects of vitamin E supplementation on maternal and neonatal vitamin E status. Studies were systematically searched in PubMed, Scopus, Web of Science, EMBASE, LILACS, and the Cochrane Library. Randomized controlled trials (RCTs) comparing vitamin E supplementation in pregnant women with placebo were included. Study selection, data extraction, and risk of bias assessment using the Cochrane Risk of Bias tool were independently performed by reviewers. Meta-analyses were conducted using RevMan 5.4, and the certainty of evidence was assessed using the GRADE approach. Six RCTs including 3.823 pregnant women met the inclusion criteria. Vitamin E supplementation significantly increased maternal serum α-TOH concentrations (SMD = 4.89; 95% CI: 2.89-6.89;
