Sleepiness, sleep deprivation, quality of life, mental symptoms and perception of academic environment in medical students.
Trial report in BMC medical education, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06260280 (Relationship Between Chronic Sleep Deprivation and Changes in Cortical and Hippocampal Volume Assessed by Nuclear Magnetic Resonance in First-Year Medical Residents), which is not on this map. Cited by 69 papers, 3 of them syntheses that pooled 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.
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.

Abstract
backgroundIt has been previously shown that a high percentage of medical students have sleep problems that interfere with academic performance and mental health.
methodsTo study the impact of sleep quality, daytime somnolence, and sleep deprivation on medical students, we analyzed data from a multicenter study with medical students in Brazil (22 medical schools, 1350 randomized medical students). We applied questionnaires of daytime sleepiness, quality of sleep, quality of life, anxiety and depression symptoms and perception of educational environment.
results37.8% of medical students presented mild values of daytime sleepiness (Epworth Sleepiness Scale - ESS) and 8.7% presented moderate/severe values. The percentage of female medical students that presented ESS values high or very high was significantly greater than male medical students (p < 0.05). Students with lower ESS scores presented significantly greater scores of quality of life and perception of educational environment and lower scores of depression and anxiety symptoms, and these relationships showed a dose-effect pattern. Medical students reporting more sleep deprivation showed significantly greater odds ratios of presenting anxiety and depression symptoms and lower odds of good quality of life or perception of educational environment.
conclusionsThere is a significant association between sleep deprivation and daytime sleepiness with the perception of quality of life and educational environment in medical students.
