A study protocol for a randomized controlled trial to assess the efficacy of family-based treatment for preventing overweight or obesity among children and adolescents in China.
Article in BMC public health, 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
backgroundFamily-based treatment (FBT) that teach behavioral techniques, focusing on integrating behavior changes into daily routines and delivered in a family-based format-targeting both child and parent-appear to be the most effective treatment for childhood obesity. This study aims to assess the efficacy of FBT for preventing overweight or obesity among children and adolescents in China.
methodsThis is a 24-months randomized controlled trial (RCT). School-aged children and their parents will be screened for overweight or obesity. 200 parent-child pairs with overweight or obesity will be enrolled and randomly assigned (1:1) into the FBT Group, and the Usual Care (UC) Group. Participants in the UC group receive the UC intervention, while those in the FBT group receive both the UC and FBT. The primary outcomes are body mass index (BMI) and normal weight (assessed as BMI) percentages during the 24-month period. The secondary outcomes are waist circumference, body composition, blood test, dietary habits, levels of physical activity, and psychological well-being during the 24-month period. DISCUSSION: This study is the first long-term RCT to apply FBT for the preventing overweight or obesity among children and adolescents in China. The study offers novel and immediately useful information to families, healthcare providers, and medical organizations through the development and optimization of evidence-based FBT. It also provides an opportunity to assess the effectiveness of FBT implemented in both routine clinical practice and family environments for Chinese children and adolescents suffering from overweight and obesity.
