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

Sleep is a vital physiological process affecting physical, mental well-being, and cognitive performance, but it is not well studied in Vietnam medical students. Therefore, we aimed to assess the prevalence of poor sleep quality among Vietnamese medical students and identify associated factors. A cross-sectional study was conducted from April to May 2024 among all medical students at the University of Danang, Vietnam. Data were collected using a self-administered questionnaire about the Pittsburgh Sleep Quality Index (PSQI), demographic, mental health, and sleep-related characteristics. Poisson regression was used to identify factors associated with poor sleep quality (PSQI > 5). The study found that 45.8% of participants (264/577) (95% CI: 41.7-49.8%) had poor sleep quality, with a mean PSQI score of 5.4 ± 2.3. Clinical students had a higher prevalence of poor sleep quality (51.8%) than preclinical students (40.0%) (p = 0.005). In multivariable analysis, clinical training (PR = 1.37; 95%CI: 1.14-1.65), lower academic performance (PR = 1.43; 95%CI: 1.08-1.89), noise (PR = 1.49; 95%CI: 1.19-1.86), light disturbance during sleep (PR = 1.26; 95%CI: 1.04-1.53), stress (PR = 1.22; 95%CI: 1.00-1.48), anxiety (PR = 1.43; 95%CI: 1.15-1.78), and depression (PR = 1.29; 95%CI: 1.07-1.57) were significantly associated with poor sleep quality. In conclusion, poor sleep quality was highly prevalent, especially among clinical-year students.
