The influence of physical exercise on attentional bias: a systematic review and meta-analysis.

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: Attentional bias refers to the tendency to prioritize attention toward negative or threatening stimuli rather than positive or neutral ones. It is closely linked to a range of psychological and behavioral disorders. Physical exercise, a behavior beneficial to both physical and mental health, has been shown to influence attentional bias. This study aims to systematically review the literature and conduct a meta-analysis on the relationship between physical exercise and attentional bias, providing a comprehensive overview of current research in this field. Objective: To investigate the relationship between physical exercise and attentional bias across different populations, thereby providing insights for interventions targeting psychological distress and maladaptive behaviors. Methods: Literature was retrieved from eight databases, followed by study screening, data extraction and analysis. A qualitative synthesis was conducted, while a quantitative analysis of relevant variables was performed using meta-analysis. Results: A total of 32 studies were included in this review. Physical exercise was found to reduce negative attentional bias in individuals with anxiety, depression, and high psychological stress, alleviating symptoms of these conditions. However, physical exercise did not significantly reduce negative attentional bias in obese or overweight individuals. It also reduced attentional bias towards addiction-related cues in addicted individuals and alleviated craving for addictive substances or behaviors. Furthermore, it reduces negative attentional bias and enhances positive attentional bias in healthy individuals, thereby promoting healthy behaviors. The effect of physical exercise on negative attentional bias appears to be modulated by exercise intensity, with moderate-intensity exercise demonstrating superior efficacy. In contrast, acute high-intensity exercise can increase an individual's negative attentional bias. Conclusion: Moderate-intensity physical exercise appears effective in reducing negative attentional bias and enhancing positive attentional bias, particularly when assessed using emotionally salient image stimuli. However, effects may be attenuated or reversed under conditions of high-intensity exercise, abstract verbal stimuli, or in specific populations such as obese individuals undergoing high-energy expenditure. Therefore, moderate-intensity exercise may serve as an effective intervention for improving psychological and behavioral disorders.
