Multiple Health Outcomes of Daytime Napping: A Comprehensive Umbrella Review.
Review in Public health reviews, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Objectives: This umbrella review aimed to clarify the dose-response relationship between napping duration and multiple health outcomes. Methods: Following JBI guidelines, the review included studies from PubMed, Web of Science, the Cochrane Library, and EMBASE. Data on health outcomes, effect sizes, and study characteristics were extracted, and the quality of the studies was assessed using AMSTAR-2 and GRADE. A random effects model and a sensitivity analysis were used to evaluate the associations. Results: This umbrella review identified 16 meta-analyses encompassing 244 health-related outcomes. Napping for <60 min maximizes cognitive enhancement (SMD = 0.69, 95% CI: 0.37-1.00) and reduces fatigue, while minimizing the risk of all-cause mortality and chronic diseases. Napping for >60 min correlates with a 30% higher risk of coronary heart disease and a 20% increased risk of diabetes and obesity; short naps (20-30 min) improve athletic performance (SMD = 0.99, 95% CI: 0.67-1.31) and recovery, particularly in sleep-deprived individuals. Conclusion: Limiting nap duration to ≤60 min may optimize cognitive and physical benefits while reducing chronic disease risks. For individuals with chronic conditions, it is prudent to avoid prolonged naps (>60 min) and prioritize nighttime sleep quality.
