Development of a Deep Learning Model for Predicting Obesity Using Health Behavior Data of Elementary School Students.
Article in Iranian journal of public health, 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
Background: Childhood obesity poses serious long-term health risks and is a growing global concern. In South Korea, national health surveys collect behavioral and physical data from elementary students, but the large number of questionnaire items can burden young respondents and reduce accuracy. Thus, simplified models with high predictive power are needed. Methods: We analyzed data from over 250,000 elementary students collected by the Korean Ministry of Education (2015-2022). Using the Rohrer Index as the outcome variable, key predictors were selected via Lasso and Elastic Net regression. Categorical variables were reduced using Multiple Correspondence Analysis (MCA), and a deep learning model (NECTOR) combining MLP and self-attention was developed. Results: NECTOR achieved high predictive performance with R Conclusion: A small set of core health indicators can effectively predict the Rohrer Index. The proposed model enables efficient and reliable obesity screening in school settings, supporting early intervention efforts.
