Psychological consequences of insufficient sleep in medical students.
Article in Discover mental 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
backgroundInsufficient sleep is a common public health issue among students, and it is necessary to investigate this phenomenon and its consequences. Therefore, the present study aimed to examine the psychological consequences (i.e., somatization, depression, anxiety, and hostility) of insufficient sleep in medical students.
methodsThe sample in this cross-sectional study consisted of 448 college students (with a mean age of 23.47 years; 56.7% female) from Kermanshah University of Medical Sciences at Iran. Symptom Checklist-90-Revised Form (SCL-90-R) and several self-report questionnaires (physical activity, bedtime, sleep duration, and daily nap) were used to collect data, and the results were analyzed using ANOVA and ANCOVA.
resultsThe results showed statistically significant differences in the mean scores of anxiety (F = 10.84, η
conclusionAccording to the results, insufficient sleep and short sleep duration are significantly associated with elevated anxiety, depression, somatization, and hostility. A key limitation is the reliance on a single self-report item for assessing sleep duration, which is subject to recall bias. Future longitudinal studies with objective sleep measures be conducted to explore the causal links between sleep duration and mental health.
