Prevalence and correlates of restless leg syndrome in psychiatric outpatients in Lebanon.
Article in Scientific reports, 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
Restless Legs Syndrome (RLS) is a prevalent yet underdiagnosed neurological disorder that significantly affects quality of life. It is commonly associated with psychiatric conditions, particularly depression and anxiety. Epidemiological data on RLS prevalence among psychiatric populations are limited and virtually absent in Lebanon. This study estimated RLS prevalence among psychiatric outpatients and assessed its impact on sleep quality, daytime sleepiness, anxiety, and depression, comparing findings to international literature. In this cross-sectional study, adult psychiatric outpatients were screened using International Restless Legs Syndrome Study Group (IRLSSG) criteria. Additional questionnaires included the Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), Patient Health Questionnaire-9(PHQ-9), and Generalized Anxiety Disorder-7(GAD-7). Bivariate analysis compared patients with and without RLS. Multivariate regressions were utilized to adjust for potential confounders. Of 130 participants 25.4% had RLS. These patients showed significantly poorer sleep (PSQI = 11.18vs.8.10, p = 0.002), more depressive symptoms(PHQ-9 = 15.52vs.9.88,p < 0.001), and greater anxiety(GAD-7 = 15.26vs.9.51,p < 0.001), however, no significant difference was found in daytime sleepiness (ESS = 8.42vs.7.63,p = 0.405 ). RLS was significantly associated with suicidal ideation(p < 0.001). Correlation analysis revealed significant associations between RLS severity and both sleep disruption and psychiatric symptom severity. In conclusion, RLS is highly prevalent among psychiatric outpatients in Lebanon and is strongly associated with worse mental health and increased suicidal ideation.
