1 · What the graph read from it

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.

2 · The registry

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: Bruxism is a repetitive jaw-muscle activity characterised by clenching or grinding of the teeth and/or by bracing or thrusting of the mandible. Current international consensus regards it as a motor behaviour rather than a disorder, and one that may act as a risk factor for tooth wear and temporomandibular disorders; psychosocial stress is among its most consistently reported associated factors. Clinical-year dental and medical students face intense academic and clinical pressure that may predispose them to both stress and bruxism, yet no published Ghanaian data on this relationship previously existed. Methods: A cross-sectional study was conducted among clinical-year (4th-6th year) dental and medical students at the University of Ghana, Korle Bu campus. A stratified sample of 291 students, proportionally allocated by course and clinical year, completed a self-administered online questionnaire comprising a 12-point bruxism knowledge module, a 10-item bruxism symptom screening module and the 30-item Perceived Stress Questionnaire (PSQ). Prevalence estimates are reported with 95% confidence intervals (CIs). Associations were examined using chi-square tests, multivariable linear regression, and Pearson and Spearman correlation coefficients, at Results: Participants had a mean age of 23.6 ± 2.3 years; 55.0% were male, and 85.2% were medical students. Only 19.6% (95% CI: 15.4%-24.5%) demonstrated good knowledge of bruxism, with dental students (48.8% vs. 14.5%, Conclusion: Knowledge of bruxism is markedly poorer among medical than dental students, and among junior compared with final-year trainees. Self-reported bruxism symptoms are common despite a low rate of high perceived stress, and stress shows a modest but significant positive association with bruxism. Curricular bruxism education for medical students and proactive stress-reduction initiatives are warranted.
