Social Media Use and Jaw Motor Activity: Insights From Electromyography and Self-Report Data.
Article in Journal of oral rehabilitation, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundOral behaviors (OBs) are recognized risk factors for temporomandibular disorders. Social media use has been reported to be linked with stress, a key regulator of jaw motor activity. Whether social media use increases the incidence of OBs remains undetermined.
objectiveTo investigate the impact of social media use on jaw motor activity.
methodsSeventy-two individuals (36 females, 36 males; 22.4 ± 2.8 years) completed an online survey assessing their screen habits and OBs using the oral behaviour checklist (OBC). A subset of 30 healthy participants (15 females, 15 males; 22.2 ± 2.0 years) completed an in-person experimental session involving three 30-min tasks (silent reading, using social media and watching a documentary on TV). The electromyographic (EMG) activity of the right masseter was measured throughout the session. OBs were identified as events with EMG amplitude exceeding 10% of the participants' maximum voluntary contraction (MVC) lasting at least 2 s. General linear and mixed-effect models were used to test relationships between screen habits, OBC scores, and task-related EMG metrics.
resultsMean ± SD daily social media use was 154 ± 73 min on weekdays and increased to 185 ± 85 min on weekends (p < 0.001). Time spent on social media was a significant but weak predictor of OBC scores (B = 0.042, SE = 0.014, t = 3.009; 95% CI = 0.014-0.070; p = 0.004). No significant differences in OB frequency, duration, or amplitude were observed across experimental tasks (all p > 0.05).
conclusionWhile social media use was modestly associated with self-reported OBs, it did not significantly affect jaw motor activity in a controlled experimental setting. Further studies using ambulatory EMG recordings are recommended.
