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

backgroundObstructive sleep apnea (OSA) and sleep bruxism (SB) are both sleep-related conditions that may affect sleep architecture and potentially contribute to daytime sleepiness (DS).

aimThis study aimed to explore the association between SB and DS as measured by Epworth Sleepiness Scale in patients with OSA.

methodsA cross-sectional study was conducted involving 345 patients diagnosed with OSA. The presence of SB was assessed through multidisciplinary clinical examination and audio-video recordings during polysomnography. DS was measured using the Epworth Sleepiness Scale (ESS). Demographic and polysomnographic characteristics were compared between OSA patients with and without SB. Logistic regression models were used to identify significant associations.

resultsSB was identified in 13.6% of OSA patients. After adjusting for confounders, OSA patients with SB exhibited significantly higher ESS scores (6.44 vs. 5.28, p = 0.012) and lower percentages of REM sleep (10.23% ± 5.66 vs. 12.82% ± 7.36, p = 0.017). In patients with severe OSA, those with SB showed lower AHI values (60.28 ± 24.39 vs. 69.95 ± 25.25, p = 0.048), increased N3 sleep (18.51% ± 11.49 vs. 13.16% ± 10.13, p = 0.038), and a trend towards reduced REM sleep (9.38% ± 5.17 vs. 11.77% ± 7.08, p = 0.07).

conclusionThis study suggests a potential association between SB and daytime sleepiness as measured by ESS score, as well as alterations in sleep architecture, in OSA patients.
