The association between cardiovascular health, measured using Life's Essential 8, and obstructive sleep apnea: a cross-sectional and Mendelian randomization study.
Article in American journal of translational research, 2026. 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
backgroundCardiovascular health (CVH), operationalized using the Life's Essential 8 (LE8) construct, has been linked to a myriad of health outcomes. Although there is a link between CVH and Obstructive Sleep Apnea (OSA), which has become a significant public health issue, a thorough investigation of this relationships has not been undertaken.
methodsThis study investigates the association between CVH, quantified according to the LE8 construct, and OSA using data from the National Health and Nutrition Examination Survey (NHANES). Based on data from the NHANES (2005-2008, 2015-2018), this study consisted of 9,350 adults aged 20-79 years. Logistic regression analysis is utilized to determine the association between LE8 scores and OSA. Two-sample Mendelian randomization (MR) is used to investigate the causal relationship between CVH and OSA with the inverse-variance weight (IVW) method being the primary source of analysis.
resultsThe connection between CVH and OSA risk was affirmed, with individuals who had better CVH (high LE8 vs. low LE8), being at significantly lower risk for OSA than those with worse CVH (Odds Ratio [OR]: 0.23, 95% confidence interval [CI]: 0.18-0.30). Additionally, patients with higher LE8 scores experienced a decreased risk of OSA in a manner that was dose-dependent. The MR analysis also provided evidence of a positive correlation between BMI (genetically determined) and increased risk for OSA (OR for 1 Standard Deviation [SD] increase = 2, 95% CI: 1.81-2.21). Additionally, individuals who smoked less and exercised more showed decreased risk of OSA with respect to smoking (OR = 0.5, 95% CI: 0.32-0.79) and exercise (OR = 0.73, 95% CI: 0.54-0.99).
conclusionsThis study highlights the importance of keeping CVH in good shape (as measured by the LE8 score) to lower the risk of developing OSA.
