Mixed
Medical students with poor sleep quality demonstrated higher academic performance (GPA) compared to good sleepers.
High academic achievement in medical school may come at the cost of sleep. While poor sleepers had higher GPAs, they also had higher stress and anxiety. Balance is key.
ModerateQualifiesMEDIUM confidence
Poor sleepers demonstrated higher academic performance than sufficient sleepers (p 0.04).
Why this rating
Cross-sectional, self-reported GPA, small sample size.
