Gender and residential differences in sleep quality among Chinese adolescents aged 13-18 years.
Article in PloS one, 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
backgroundGood sleep is essential for healthy adolescent development, yet declining sleep quality among Chinese adolescents has become a nationwide public health concern. Residential setting and sex are key determinants of sleep quality; however, systematic evaluations of sleep quality across regions and between sexes among Chinese adolescents remain limited.
methodsData were collected on Pittsburgh Sleep Quality Index (PSQI), body mass index (BMI), Physical Fitness Index (PFI), sedentary time, screen time, and mental health from 5,713 adolescents (mean age, 15.11 ± 1.70 years). Logistic regression models were applied to examine the effects of these factors on adolescent sleep quality, including interactions with residence and gender.
resultsOverall, 33.71% of Chinese adolescents exhibited poor sleep quality. The prevalence of poor sleep quality was 35.78% among rural adolescents, which was significantly higher than that among urban adolescents (p < 0.001). Among females, 38.40% were classified as having poor sleep quality, a proportion significantly higher than that among males (p < 0.001). BMI, PFI, moderate-to-vigorous physical activity (MVPA), sedentary time, screen time, and mental health scores were significantly effects on the PSQI global score and its component scores (p < 0.05). Residence and gender significantly moderated the linear associations between sleep quality and BMI, PFI, MVPA, sedentary time, and mental health scores (p < 0.05).
conclusionsChinese adolescents living in rural areas and female adolescents experience a greater burden of poor sleep quality. Mental health and PFI appear to be protective factors for sleep quality, whereas BMI, sedentary time, and screen time are risk factors among Chinese adolescents. Moreover, these associations are moderated by residence and gender.
