Body composition among 6-7 years-old children: data from the 2015 Pelotas (Brazil) Birth Cohort Study.
Article in BMC pediatrics, 2026. 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
backgroundNutritional assessment of children is essential for health, especially given the observed worldwide increase in childhood overweight and obesity. This study aims to describe body composition (fat and lean mass) in children aged 6–7 from the 2015 Pelotas (Brazil) Birth Cohort.
methodsLongitudinal study that measured fat mass (FM% and FM in kilograms) and lean mass (LM% and LM in kilograms) using Dual-Energy X-ray Absorptiometry (DEXA) and Air-Displacement Plethysmography (BodPod). Body composition was described in relation to the independent variables. Student t-tests were used for binary variables, and ANOVA was used for categorical and ordinal variables.
resultsOf the 4,275 children included in the original cohort, 2,271 had DEXA, and 2,181 had BodPod data at age 6–7 years. Overall, BodPod and DEXA measures presented similar results, with girls having a higher average fat mass percentage in BodPod [25.2% (95%CI 24.7; 25.7) and DEXA [25.9% (95%CI 25.3; 26.4)]. Boys had a higher average lean mass percentage for both equipment [BodPod: 80.5% (95%CI 79.9; 81.1) and DEXA: 74.6% (95%CI 74.1; 75.2)].
conclusionChildren classified as obese, according to BMI-for-age z-score, had a higher average fat mass percentage (DEXA: 37.2% and BodPod: 34.5%), and this mean was higher among girls. The FM% was higher among girls and LM% among boys. Classifications of body composition in children are needed.
