Association between restless legs syndrome and sleep quality in Peruvian medical students.
Article in PloS one, 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
objectiveTo evaluate the association between restless legs syndrome (RLS) and sleep quality in Peruvian medical students.
methodsCross sectional study with a secondary data analysis. The study included Peruvian medical students surveyed in 2020. The outcome was sleep quality evaluated using the Pittsburgh Sleep Quality Index (PSQI), and the exposure variable was RLS assessed with the International Restless Legs Syndrome Study Group (IRLSSG) scale. To address the research question, we employed Poisson regression models with robust variance.
resultsWe analyzed information from 3139 medical students (61.1% female, median age 22.3 years). 15.3% experienced symptoms of Restless Legs Syndrome (RLS), and 77.2% had poor sleep quality. The prevalence of poor sleep quality was higher in female participants (80.0%) and those with symptoms of anxiety (92.8%), depression (91.6%), and severe nomophobia (86.3%). In the multivariable model, the presence of RLS symptoms was associated with poor sleep quality (prevalence ratio: 1.05, 95% CI 1.01 - 1.09, p < 0.013).
conclusionWe found a high prevalence of poor sleep quality, notably associated with RLS. Other factors associated with poor sleep quality were the academic year of study, anxiety, depression, and nomophobia.
