Rapid weight gain in first 2 years of life and BMI trajectories from 3 to <10 years: a population-based longitudinal study of 1.7 million Brazilian children.

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
Background: Obesity is considered a disease with negative health impacts at all life stages. Changes in growth patterns, such as postnatal rapid weight gain (RWG), can be important predictors of growth trajectories in children. We investigated the association between RWG during the first two years of life and subsequent BMI trajectories from the age 3-to 9 years, and whether the association differed by birth weight group. Methods: We used the data of a population-based cohort from the Cadastro Único (CadÚnico) of the Federal Government, the linkage of the National Live Births System (SINASC) and the National Food and Nutritional Surveillance System (SISVAN). The sample comprised 1.7 million Brazilian children aged from zero to nine years from 2008 to 2017. Mixed-effects models were used to estimate mean age-trajectories for BMI by RWG group. Findings: Children who experienced RWG during the first two years of life had higher mean BMI trajectories from 3 to 9 years, compared to those who did not. The difference was seen across all birth weight groups, and was more evident for the children with high birth weight. At age 9, the BMI difference between RWG and non-RWG children was 1.31 kg/m Interpretation: Children who experienced RWG during the first two years of life had higher BMI trajectories than children who did not. The finding highlighted the importance of monitoring child growth, which allows the early identification of potential growth deviations and the implementation of necessary interventions to ensure that children grow healthy and reach their full developmental potential.
