Daytime Napping in Adults: Benefits or Risks? Insights from Mendelian Randomization Studies.
Article in Current sleep medicine reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Purpose of review: Daytime napping, a brief sleep episode during the day, has mixed health effects. This review explores the relationship between daytime napping frequency and health outcomes by synthesizing results from published Mendelian randomization (MR) studies, which help mitigate confounding and reverse causality commonly observed in traditional epidemiological research. Recent findings: A total of 35 studies spanning seven major disease categories were identified, with cardiovascular, neurological, and metabolic outcomes being the most frequently investigated in MR. Of the 89 tested outcomes, 36% of studies suggested increased disease risk with more frequent daytime napping, 54% reported no associations, and 10% suggested decreased disease risk with more frequent daytime napping. Not all MR findings align with existing epidemiological research. Summary: The current evidence from MR does not provide a definitive conclusion regarding the health effects of daytime napping. Future research should consider additional dimensions of napping beyond frequency and integrate both genetic and non-genetic approaches in diverse populations.
