The effect of the arousal threshold on sleep bruxism intensity in coexisting sleep apnea and sleep bruxism: a polysomnographic study.
Observational study in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
Obstructive sleep apnea (OSA) is often accompanied by sleep bruxism (SB). A low respiratory arousal threshold (AT) may contribute to the induction or exacerbation of SB. The aim of this study was to assess the impact of the AT on the intensity of bruxism in individuals with OSA and SB. The prospective observational study was undertaken in 117 subjects with suspected sleep disorder (47% females, average age 44.83 years) who undergone video-polysomnography. Among the study participants, 77 (64.1%) were found to have a low AT, while 42 (35.9%) had a high AT. Participants with low AT's had significantly higher bruxism episode index (BEI) and phasic BEI values than patients with a high AT (6.06 ± 4.46 vs. 4.54 ± 3.18; p = 0.04 and 3.18 ± 3.49 vs. 1.84 ± 1.74; p = 0.03, respectively). The positive correlation between BEI and a low AT and a higher percentage of hypopneas were found (R = 0.190, p = 0.040; R = 0.278, p = 0.002, respectively). Summarizing, there is a higher intensity of SB observed in patients with a low AT, than in those with a high one. This effect is more pronounced in men. SB accompanying low AT may be a protective factor in OSA patients, by terminating respiratory events. Thus patients with a low AT and SB could be better protected from OSA complications.
