Satisfaction with Life in relation to Sleep Health among a Nationally Representative Sample of U.S. Adults.
Article in medRxiv : the preprint server for health sciences, 2025. 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
Purpose: To investigate associations between life satisfaction and sleep health among adults in the United States. Methods: We analyzed cross-sectional, nationally-representative data from the 2022 National Health Interview Survey. Life satisfaction was dichotomized as 'very satisfied/satisfied' vs. 'dissatisfied/very dissatisfied.' Sleep duration was defined as 'recommended' vs. 'short' (≥7 vs.<7 hours), frequent insomnia symptoms as difficulty falling/staying asleep: 'yes' [most days/every day to either] vs. 'no' [never/some days for both]), and restorative sleep as feeling well rested in the past 30 days: 'yes' [never/some days] vs. 'no' [most days/every day]. Using survey-weighted Poisson regression with robust variance adjusting for confounders, we estimated prevalence ratios (aPR) and 95% confidence intervals (CI) overall and by age, sex, race, and ethnicity to test for effect modification. Results: Among 25,090 adults (mean age of 48.1±0.17 years; 54% women), 96.0% reported life satisfaction with comparable prevalence across age: 18-30 years [96.3%], 31-49 years [96.6%], and ≥50 years [95.3%]; and among men [95.8%] along with women [96.1%]. Prevalence by race and ethnicity ranged from 93.5% [non-Hispanic (NH)-Multiracial/other] to 98.3% [NH-Asian]. Life satisfaction vs. dissatisfaction was associated with recommended sleep duration (aPR:1.14 [95% CI:1.07-1.21]), restorative sleep (aPR:1.61 [95% CI:1.45 -1.79]), and infrequent insomnia symptoms (aPR:1.25 [95% CI:1.16-1.33]) even after further adjustment. Although life satisfaction varied by age, sex, race, and ethnicity, they did not modify associations between life satisfaction and sleep. Conclusions: Life satisfaction was associated with recommended sleep duration, infrequent insomnia symptoms, and restorative sleep. Pathways underlying the life satisfaction-sleep relationship should be identified to inform interventions.
