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

Maternal nutrition during pregnancy plays a role in offspring bone health. In a prospective cohort study, offspring bone mineral density at 5 years was not associated with maternal calcium intake or maternal bone resorption during pregnancy. PURPOSE: Suboptimal bone mineral density in childhood can result in osteoporosis later in life. We reported previously that lower calcium intake during pregnancy was associated with higher maternal bone resorption during pregnancy and that lower maternal dietary calcium and higher maternal bone resorption in pregnancy were associated with lower maternal bone mineral density (BMD) 5 years later. The current study sought to investigate the effect of both maternal dietary calcium intake and maternal bone resorption during pregnancy on offspring BMD at 5 years.

methodsData collected as part of the ROLO longitudinal cohort study (n = 103, mother-child dyads) were used in the current analysis. ROLO started as a randomised controlled trial of a low glycemic index diet during second pregnancy in women with macrosomia in first pregnancy in order to prevent recurrence of macrosomia. Maternal dietary intakes were assessed using 3-day food diaries completed during each trimester of pregnancy. Bone resorption in early and late pregnancy was calculated through urinary excretion of cross-linked N-telopeptides (uNTX). Offspring whole-body BMD at 5 years was measured using dual-energy X-ray absorptiometry.

resultsOffspring BMD at 5 years correlated with offspring body mass index (r = .385; p < .001) and offspring BMD was higher in boys than girls (t = 2.91; p = .004). Offspring BMD at 5 years was not associated with either maternal calcium intake or uNTX during pregnancy, after controlling for offspring body mass index and offspring sex.

conclusionOffspring BMD at 5 years is not associated with either maternal calcium intake or maternal bone resorption during pregnancy.
