Exploring the Link Between Headache, Possible Sleep Bruxism and Self-Medication in Adolescents.

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
aimAdolescents predominantly suffer from headaches and sleep bruxism. Yet, the association between both conditions remains unclear. This study investigated the relationship between primary headaches and possible sleep bruxism in adolescents.
methodsA cross-sectional study was conducted from August 24 to October 13, 2022, with 567 adolescents (aged 14-19 years old) from public schools in Recife, Brazil. Data were collected via questionnaires on sociodemographic characteristics, self-medication and the Paediatric Migraine Disability Assessment. Possible sleep bruxism was diagnosed based on international consensus criteria. Pearson's chi-square test and multivariate analysis were used for statistical evaluation (p < 0.05).
resultsThe sample comprised 567 students, predominantly female (54.1%) and aged 16-17 years old (65.1%). Most attended school full-time (61.6%), had employed guardians (57.5%) and had a family income around the minimum wage (44.3%). Possible sleep bruxism was identified in 10.6% of adolescents, while headaches affected 40.6%. Over-the-counter medication use was reported by 70.2%, with 68.8% specifically self-medicating for headaches. Headaches were associated with gender, guardian's employment status, possible sleep bruxism and self-medication for headache (p < 0.05).
conclusionPrimary headaches were associated with possible sleep bruxism. Female adolescents and those with possible sleep bruxism were nearly twice as likely to experience headaches.
