A systematic review of ego depletion phenomenon in group-based hierarchical relations.
Synthesis 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
Introduction: This systematic review examines the relationship between intergroup relations and ego depletion, aiming to understand how self-control resources are affected in social hierarchies. Methods: A total of 35 peer-reviewed articles and four unpublished doctoral dissertations were reviewed. Findings were categorized based on the social position of the target person's group in intergroup interactions. Results: Intergroup contacts depleted the self-control resources of dominant group members when they were required to suppress biases. For subordinate group members, engaging in intergroup interactions, witnessing bias, or facing bias threats also depleted self-control resources. Depleted dominant members exhibited increased prejudice and stereotyping, whereas depleted subordinate members showed lower perception of prejudiced behaviors and higher liking for dominant group members. Discussion: The findings are interpreted within the framework of social dominance theory, highlighting how ego depletion influences intergroup relations and reinforcing the role of group-based hierarchies in shaping social behavior.
