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

objectivesTo determine the association between total breastfeeding duration and serum 25-hydroxyvitamin D (25-OHD) and to explore whether vitamin D supplementation influences this association.

methodsWe conducted a cross-sectional study of healthy children between September 2011 and August 2013 through the TARGet Kids! primary health care research network. Of the 4533 eligible children, we included only the 2508 who had 25-OHD measured. We assessed adjusted associations of total breastfeeding duration (in months) with serum 25-OHD and in supplemented versus nonsupplemented children, with the odds of 25-OHD less than 20 nanograms per milliliter.

resultsEach 1-month increase in total breastfeeding duration was associated with a 0.12 nanograms per milliliter lower median serum 25-OHD (95% confidence interval [CI] = -0.21 ng/mL, -0.02 ng/mL) among children who were not supplemented. The odds of serum 25-OHD less than 20 nanograms per milliliter increased by 6% (odds ratio [OR] = 1.06; 95% CI = 1.03, 1.10) for every 1-month increase in total breastfeeding duration among nonsupplemented children. The interaction between vitamin D supplementation, duration of breastfeeding, and median serum 25-OHD was statistically significant (P = .04).

conclusionsBreastfed children who were not supplemented, particularly those breastfed more than 1 year, appear to have lower vitamin D status. Vitamin D supplementation may mitigate this risk. These findings support recommendations for supplementation during breastfeeding of any duration.
