Behavioral and psychosocial correlates of awake bruxism behaviors in esports athletes: a cross-sectional study.
Article in Scientific reports, 2026. 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
Awake bruxism (AB) has been little explored in esports. This study estimated the frequency of self-reported AB behaviors, described behavioral features, and identified associated factors in esports practitioners. In this cross-sectional study, 447 esports players from São Paulo, Brazil, completed self-report questionnaires using items derived from the BruxScreen protocol and the Standardized Tool for the Assessment of Bruxism (STAB). AB behaviors were assessed using a frequency-based approach, and participants were stratified into low- and high-frequency groups. Overall, 35% met the criterion for frequent AB. Compared with low-frequency individuals, high-frequency participants more often reported clenching (46.7% vs. 9.1%) and daily mandibular pain (39.1% vs. 7.2%). Behavior frequency correlated with previous AB history (ρ = 0.49), psychological distress (ρ = 0.42), and gastroesophageal symptoms (ρ = 0.37) (all p < 0.001), while male sex showed an inverse correlation (ρ = - 0.27; p < 0.001). In multivariable regression, previous AB history (B = 0.75; 95% CI 0.55-0.95), psychological distress (B = 0.06; 95% CI 0.03-0.10), and gastroesophageal symptoms (B = 0.24; 95% CI 0.11-0.36) remained independently associated (p < 0.001). The model explained 36% of the variance. AB behaviors are common in esports and reflect a multifactorial phenomenon influenced by psychosocial and contextual factors, supporting the need for preventive and educational strategies in this population and clinical awareness.
