Total cholesterol/high-density lipoprotein cholesterol-related indices as predictors of obstructive sleep apnea and cardiovascular mortality: A cross-sectional study.

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
The relationship between the total cholesterol/high-density lipoprotein cholesterol (TC/HDL) and TC/HDL with the combination of obesity indicators and obstructive sleep apnea (OSA) remains unclear. Therefore, we aimed to explore the associations between TC/HDL-related indices and OSA as well as clinical outcomes. This study enrolled 20,076 patients from the National Health and Nutrition Examination Survey (2005-2008 and 2015-2018). Three indicators were constructed including TC/HDL index, TC/HDL combining with relative fat mass (TC/HDL-RFM), and TC/HDL combining with body mass index (TC/HDL-BMI). We performed multivariable logistic regression and generalized additive models to evaluate the association between TC/HDL-related indices and OSA. Multivariable Cox proportional hazards regression models with restricted cubic splines were performed to assess the relationships between TC/HDL-related indices and mortality. Stratified analyses were conducted to further investigate population-specific differences. The multivariable logistic regression analyses showed that high levels of TC/HDL-related indices were significantly associated with increased prevalences of OSA (TC/HDL: odds ratio [OR] per 1 standard deviation [SD] increase: 1.1, 95% confidence interval [CI]: 1.07-1.14, P < .001; TC/HDL-RFM: OR per 1SD increase: 1.22, 95% CI: 1.18-1.27, P < .001; TC/HDL-BMI: OR per 1SD increase: 1.28, 95% CI: 1.23-1.33, P < .001). Inverted U-shaped curves were depicted between TC/HDL-related indices and OSA. During a mean follow-up of 91 months, 1917 (9.5%) all-cause deaths occurred, and 567 (2.8%) were contributed to cardiovascular deaths. Meanwhile, the TC/HDL-related indices were associated with cardiovascular mortality, but not with all-cause mortality. Subgroup analyses showed that the strength of this relationship was found to be more pronounced in participants with OSA. The TC/HDL-related indices were independent predictors of OSA and cardiovascular mortality. Our study indicated that TC/HDL-related indices can assist clinicians in making more informed clinical decisions for patients with OSA and help reduce the risk of cardiovascular mortality.
