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
backgroundthe growing prevalence of paediatric obesity represents a problem of considerable urgency, with potential repercussions on the health of the individual in both the short and long term. The aim of this study was to identify risk factors associated with the development of obesity and overweight in children at age six years.
methodsthis longitudinal observational study included 8,621 out of 15,903 children born in Trentino region between 1st January 2010 and 31st December 2012 and still alive and resident in the same region at the age of 6, with a coverage of 54.2%. Data from the Italian Birth Attendance Certificate database and the Health Surveillance Forms filled out by paediatricians during the 12-month and 6-year check-ups were collected. Two multivariable models on the estimation of Prevalence Ratios (PRs) were conducted to identify independent predictors of the probability of presenting obesity or overweight at 6 years of life, separately.
resultsUsing the threshold values of the International Obesity Task Force as a reference, the prevalence of overweight and obesity at 6 years of age was 15.7% and 6.7%, respectively. Among prenatal factors, pre-pregnancy maternal body mass index (BMI) and the presence of gestational diabetes were found to positively influence the risk of obesity at 6 years. Regarding postnatal factors, birth weight, being the firstborn, male gender, as well as a BMI exceeding 2 standard deviations at 12th month of life were identified as risk factors for obesity. South American ethnicity, low maternal education, smoking during pregnancy and a smoking habit by at least one parent were also identified as risk factors for obesity. Similar results were obtained for the risk of overweight.
conclusionsthe record linkage of routine paediatric healthcare data has made it possible to identify the updated prevalence of obesity and overweight in 6-year-old children and to anticipate the timing of interception of these children (pre-school age).
