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: Attention-deficit/hyperactivity disorder (ADHD) is a prevalent neurodevelopmental condition characterized by symptoms of inattention, disorganization, and/or hyperactivity-impulsivity. Bruxism, defined as repetitive masticatory muscle activity involving clenching or grinding of the teeth and/or forceful mandibular movements, has been associated with several physiological and psychosocial factors. Considering the neurobehavioral profile of individuals with ADHD, a possible association between ADHD and bruxism has been hypothesized. Aims: To determine whether an association exists between ADHD and bruxism. Methods: A comprehensive literature search was conducted across five electronic databases and two gray literature sources. Observational studies comparing individuals with ADHD to non-ADHD controls, with data on the presence of bruxism, were included. Independent authors conducted study selection and data extraction. Risk of bias was assessed using the JBI critical appraisal tools. A pairwise meta-analysis was performed using RevMan Web. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using a random-effects model. Results: Sixteen studies with 16,348 participants were included. The pooled OR indicated that individuals with ADHD were two times more likely to present bruxism compared to controls (OR 2.16; 95% CI 1.72-2.71; p < 0.00001, I2 51%). Subgroup analyses by age group showed a consistent association across children, adolescents, and adults. Moderate heterogeneity and potential small-study bias (with little impact on the pooled results after sensitivity analysis) were observed. Conclusions: Current evidence supports a possible association between ADHD and bruxism.
