Infant body composition in a randomised trial of a maternal nutritional supplement during preconception and pregnancy.
Trial report in World journal of pediatrics : WJP, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundIn a multinational randomized controlled trial, we previously showed that maternal supplementation with myo-inositol, probiotics, and micronutrients was associated with reduced incidence of rapid infant weight gain and high body mass index (BMI) at two years among offspring. It was unclear whether these differences in weight gain and body mass were due to reduced adiposity. Therefore, we aimed to determine whether there were any differences in body composition.
methodsBody composition was measured using bioelectrical impedance spectroscopy at six weeks, six months, one year, and two years among offspring born to mothers who received a nutritional intervention (n = 268) or control (n = 264) supplement preconception and during pregnancy.
resultsThere were no group-level differences in body composition, except at two years, when fat-free mass was greater among control offspring [adjusted mean difference (aMD) 0.14 kg, 95% confidence interval (CI) 0.03, 0.25, P = 0.012]. However, there were no differences in mean percentage fat mass (%FM) at any time. In both groups, rapid weight gain [Δ weight > 0.67 standard deviation (SD) from birth to one year] was associated with greater %FM (aMD 2.0% at six months, 2.0% at one year, 1.4% at two years) compared with those who did not have rapid weight gain. Likewise, high BMI (≥ 95 percentile) at two years was associated with greater %FM (aMD 2.5%).
conclusionsA maternal nutritional intervention did not lead to differences in average offspring body composition in the first two years of life. However, fewer offspring from the supplemented group experienced rapid weight gain and high BMI, characterized by greater %FM.
