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
Current studies on Luis Suárez's three biting incidents in football reveal considerable shortcomings: an emphasis on discrete occurrences, disregard for dynamic psychological processes, and dependence on initial trait attribution. These deficiencies hinder the elucidations of recurrent unauthorised aggression by non-habitual aggressors in high-pressure situations. This research fills this need through case analysis and theoretical synthesis. Using biting occurrences as case studies, it amalgamates the self-control model and reversal theory to develop the stress-depletion-aggression model (SDA). The model outlines a three-stage hostility trajectory: (1) Internal and external stressors systematically diminish self-control resources through physiological and cognitive mechanisms; (2) Continuous depletion undermines inhibitory control and alters motivational priorities; (3) A transition in meta-motivational states (from conformist to negativistic + telic/mastery + telic) incites unsanctioned aggression. The findings indicate that the SDA model accomplishes multilevel integration of physiological, neurocognitive, and motivational factors; recognises ego depletion as the primary mediator between stress and motivational transitions; and improves predictive capability for unsanctioned aggression beyond conventional theories. The study indicates that unsanctioned aggression arises from the interactive effects of stress accumulation, resource depletion, and significant motivational-state shifts, establishing a scientific foundation for anticipating athlete hostility, formulating remedies, and optimising competition regulations. The proposed SDA model represents a novel theoretical integration, systematically combining the physiological-cognitive mechanisms of self-control resource depletion with the dynamic reversals of meta-motivational states, thereby providing a multi-level, testable framework for understanding and predicting sudden, unsanctioned aggression by non-habitual aggressors under high pressure.
