Maternal dietary flavonoid intake and child wheeze and asthma in the Conditions Affecting Neurocognitive Development and Learning in Early Childhood (CANDLE) cohort.

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
backgroundHigher intakes of flavonoids have been associated with better lung function in adults. The aim of this study was to examine the associations between maternal prenatal intake of flavonoids and offspring asthma and wheeze.
methodsWe conducted a prospective study of Black (62.8%) and White (37.2%) mother-child dyads (N = 906) enrolled in the CANDLE study. We estimated prenatal dietary flavonoid intake using the Block Food Frequency Questionnaire administered during the second trimester and subsequently linked to the United States Department of Agriculture's Provisional Flavonoid Addendum and Proanthocyanidin database. Our primary outcomes included parent report of child current wheeze and asthma (based on diagnosis, symptoms, and/or medication use) at approximately age 4 years. We used multivariable logistic regression to investigate associations between prenatal flavonoid intake and child respiratory outcomes.
resultsOverall, 19.4% and 15.8% of children had current wheeze and asthma, respectively. The highest quartile of prenatal dietary total flavonoid was associated with lower odds of childhood respiratory outcomes, relative to the lowest quartile, for current wheeze (adjusted odds ratios (aOR) [95% confidence intervals (CI)]: 0.58 [0.35, 0.96]) and current asthma (aOR [95% CI]: 0.53 [0.31, 0.91]), respectively, although there was not a clear dose-response. We observed an inverse association between the prenatal intake of proanthocyanidin and offspring current asthma, but no associations for other flavonoid subclasses.
conclusionsWe report a novel finding that children of women with the highest compared to the lowest prenatal intake of total dietary flavonoids had lower odds of current wheeze and asthma at age 4 years.
