Beyond BMI: the complex interplay of reward sensitivity, eating behaviors, and BMI in female college students.
Article in Frontiers in psychology, 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: Heightened reward sensitivity (RS) may lead to greater preference for high-calorie foods, excessive intake, and weight gain. However, the association between RS, eating behavior traits, and body mass index (BMI) remains unclear. Objective: We examined the relationship between RS and BMI and explored the associations of eating behavior traits with RS among female college students. Methods: A cross-sectional study was conducted with female students aged 18-25 years in Riyadh, Saudi Arabia. Anthropometric measurements were obtained to calculate BMI. Eating behaviors were assessed using the Three-Factor Eating Questionnaire, which measures cognitive restraint, disinhibition, and hunger. RS was evaluated using the progressive ratio task. Correlations between BMI, RS, and eating behavior traits were analyzed using non-parametric statistical methods. Results: The data of 89 students were analyzed. No significant associations were found between BMI and RS. Similarly, there were no significant correlations between RS and any of the eating behavior traits. Among the Three-Factor Eating Questionnaire subscales, only disinhibition was significantly positively correlated with BMI ( Conclusion: Although no significant associations were observed between BMI and RS or between RS and eating behavior traits, the findings contribute to understanding the complex interplay between psychological and behavioral factors in eating and weight regulation.
