Analysis of sleep quality and its influencing factors among residents in Chengguan District of Lhasa.
Article in BMC public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe aim of this study was to assess the quality of sleep and its determinants among residents of the Chengguan District in Lhasa, to provide foundational evidence for future intervention studies targeting sleep disorders in high-altitude populations.
methodsWe conducted a cross-sectional study in Chengguan District, Lhasa, between March and June 2023. Using a four-stage cluster random sampling design, 3,742 eligible residents were recruited. Data were collected using a custom Sociodemographic and Health-related Information Form and the Pittsburgh Sleep Quality Index (PSQI).
resultsThe mean Pittsburgh Sleep Quality Index (PSQI) score of the residents in the Chengguan District of Lhasa was 4.58 ± 3.03, and the prevalence rate of sleep disorders was 15.3%. Binary logistic regression analysis revealed that factors significantly correlated with sleep disorders encompassed being female, being of Han ethnicity or other ethnic minorities, possessing a high level of education, being married, divorced, or widowed, alcohol intake, taking naps lasting more than 30 min, using electronic products for over 30 min at night, suffering from chronic diseases, experiencing perceived stress, cognitive performance, engaging in shift work, and exposure to residential noise (χ² = 690.207, P < 0.001).
conclusionsThe prevalence of sleep disorders is high among residents in the Chengguan District of Lhasa. Demographic and sociological factors, lifestyle habits, physical and mental health status, occupational factors, and residential noise appear to influence sleep quality. Therefore, it would be beneficial for relevant authorities to focus on these susceptible populations in future interventions, aiming to enhance sleep quality and overall quality of life through environmental improvements, lifestyle modifications, strategic scheduling, and the provision of psychological support.
