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

background/purposeMedical students face a rigorous academic environment that often leads to compromised sleep quality, which is essential for cognitive function, mental well-being and clinical performance. Despite the importance of sleep, a significant percentage of medical students report poor sleep quality, with detrimental effects on their academic performance and overall well-being. Previous research has primarily focused on international populations, leaving a gap in understanding the sleep habits and challenges faced by Canadian medical students. METHODS AND ANALYSIS: This cross-sectional study aims to assess the sleep quality among medical students across six Canadian medical schools. The study will use validated instruments, including the Pittsburgh Sleep Quality Index and Epworth Sleepiness Scale, to measure sleep quality and daytime sleepiness. Participants will be recruited via electronic surveys distributed through email and social media. The study will collect demographic data and explore factors impacting sleep quality, such as academic workload, electronic device usage before bedtime and stress levels. Data analysis will involve stepwise multiple regressions to identify predictors of poor sleep quality. ETHICS AND DISSEMINATION: Approvals have been granted by the Research Ethics Boards at the University of Ottawa and at each participating site. Results will be reported in a peer-reviewed journal and submitted for presentation at national and international conferences.
