Grain consumption before and during pregnancy and birth weight in Japan: the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study.
Article in European journal of clinical nutrition, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
BACKGROUND/
objectivesStudies have reported the effects of grain consumption on human health, but the association between maternal grain consumption before and during pregnancy and birth weight remains unclear. We evaluated the association between maternal grain consumption before and during pregnancy and birth weight/low birth weight (LBW). SUBJECTS/
methodsGrain consumption was calculated using two semi-quantitative food frequency questionnaires (FFQs). The two FFQs evaluated consumption from pre- to early pregnancy and then from early to mid-pregnancy, respectively. Information concerning birth weight was obtained from birth records, and multivariable analyses for birth weight and LBW risk were conducted after adjusting for potential confounders.
resultsIn total, 17,610 pregnant women (age, 31.8 ± 4.9 years; smoked during pregnancy, 16.1%; gestation period, 38.5 ± 2.5 weeks; first childbirth, 45.5%) and their singleton and term new-borns (birth weight, 3061.8 ± 354.1 g; LBW, 5.4%) were included in the analysis. Women in the highest quartile of grain consumption from pre- to early pregnancy had heavier new-borns (β = 22.3; 95% confidence interval (CI): 5.8-38.9) but did not have a significantly lower LBW risk (odds ratio [OR]: 0.87; 95% CI: 0.71-1.07) than women in the lowest quartile. Women in the highest quartile of grain consumption from early to mid-pregnancy also had heavier new-borns (β = 24.1; 95% CI: 7.1-41.1) but did not have a significantly lower LBW risk (OR: 0.85; 95% CI: 0.69-1.05) than women in the lowest quartile.
conclusionsGrain consumption before and during pregnancy was positively associated with birth weight.
