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

objectivesThe objective of this cross-sectional study was to quantify the prevalence of sleep bruxism (SB) in an Egyptian population sample and to identify possible associations between SB, obstructive sleep apnea (OSA), and gastroesophageal reflux disease (GERD).

methodsThis study was conducted on patients visiting dental clinics of three governmental institutions: the National Research Centre, Cairo University, and Ain-Shams University in Egypt. All dentulous patients aged 18–70 were included in the study; those with physical or mental disabilities or genetic disorders were excluded. Validated research-made questionnaires and clinical dental examinations were used to diagnose SB, OSA, and GERD. Statistical analysis was performed to study possible associations. The significance level was set at p ≤ 0.05.

resultsNine hundred ninety-one subjects participated in this study. The prevalence of SB was 13.0%. The mean and standard deviation (SD) of the OSA score in sleep bruxers were 1.48 (1.55), as opposed to 1.35 (1.5) for non-sleep bruxers, showing no statistical significance with p = 0.388. The prevalence of GERD in the population was 22.7%; in sleep bruxers, 36.4% and in non-sleep bruxers, 20.7%, showing high statistical significance. The mean GERD score for sleep bruxers was 7.24 (2.36), as opposed to 6.69 (1.79) for non-sleep bruxers, also showing statistical significance with p = 0.002.

conclusionsThe Egyptian population has a high prevalence of SB (13.0%). An association between SB and GERD was manifested. However, no relation between SB and OSA was found.
