Assessment of Sleep Quality Among Physicians Working at Tertiary Care Centers in Saudi Arabia: A Cross-Sectional Study.
Article in Nature and science of sleep, 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
Background: Adequate sleep is essential for physicians to maintain alertness, accuracy, and emotional stability in clinical care. However, no studies focused solely on physicians, particularly in Saudi Arabia. Objective: To determine the prevalence and determinants of sleep quality among physicians in tertiary care centers in Saudi Arabia. Methods: A cross-sectional survey was conducted between January and March 2025 using the validated Pittsburgh Sleep Quality Index (PSQI). Demographic, occupational, and lifestyle data were obtained through an electronic questionnaire. Poor sleep quality was defined as a global PSQI score >5. Bivariate analyses used the chi-square test, and multivariable logistic regression estimated adjusted odds ratios (aOR) with 95% confidence intervals (CI). Results: A total of 412 physicians participated (61% male; 72% aged 20-39 years). The mean PSQI score was 8.6 ± 3.1 (median = 8), and 75.2% (95% CI: 71.1-79.4) of physicians were classified as poor sleepers. Shift work (aOR 2.58, 95% CI 1.61-4.13) and on-call duties (aOR 1.76, 1.12-2.76) significantly increased the odds of poor sleep. Later, bedtimes (1:00-3:00 AM; aOR 3.12, 1.98-4.91), prolonged daytime naps (>30 min; aOR 2.95, 1.65-5.26), and screen use before sleep (aOR 1.67, 1.08-2.61) were also associated with poorer sleep quality. Being married (aOR 0.47, 0.33-0.69), having children (aOR 0.51, 0.32-0.81), and avoiding caffeine ≥6 hours before bedtime (aOR 0.50, 0.27-0.90) were protective. Conclusion: This study highlights a high prevalence of poor sleep quality among physicians working in tertiary care centers in Saudi Arabia, driven by occupational and behavioral factors. Behavioral changes and institutional measures promoting regulated work schedules and improved sleep hygiene are essential to mitigate sleep-related risks and enhance physician well-being.
