1 · What the graph read from 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.

2 · The registry

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

backgroundA varied diet during pregnancy benefits development of the fetus, but its impact on the infant respiratory health is less well-known. This study prospectively examines the association between the maternal Minimum Dietary Diversity for Women (MDD-W) score and the risk of lower respiratory tract infections (LRTIs) in infants.

methodsThis study included 2588 women in Wuhan, China. Dietary intake was assessed using validated food frequency questionnaires. All food items were categorized into 10 groups based on guidance from the Food and Agriculture Organization to construct the MDD-W score. Infant LRTIs were recorded at 3-, 6-, and 12-months postpartum follow-ups.

resultsIn the study, 347 (13.4%) infants with LRTIs during the first year. Maternal MDD-W score ≤5 was associated with the higher risk of infant LRTIs (RR: 1.51; 95% CI: 1.11, 2.06) and hospitalization due to LRTIs (RR: 1.93; 95% CI: 1.23, 3.05) compared score ≥9. When the outcome was further subdivided into LRTIs at 0-6 months and 6-12 months of age, this association was only present at 0-6 months of age (RR: 2.02; 95% CI: 1.31, 3.10).

conclusionsOur results suggest that low maternal dietary diversity is associated with a higher risk of infant LRTIs. IMPACT: Diversified diet during pregnancy benefits the fetus's development, but few studies have demonstrated the effect of dietary diversity during pregnancy on the infant respiratory health. In this longitudinal cohort in China, we found that a varied diet during pregnancy was associated with a lower risk of infant lower respiratory tract infections, the association remained regardless of whether infants breastfed. An intervention to increase maternal dietary diversity should be carefully considered.
