Non-linear association between life's essential 8 score and depression in middle-aged and older adults with chronic obstructive pulmonary disease.

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
objectiveRelatively few studies have investigated the link between the Life's Essential 8 (LE8) score and depression among individuals with Chronic Obstructive Pulmonary Disease (COPD). Our objective was to explore the potential association between the LE8 score and the presence of depression in adults aged ≥40 years who diagnosed with COPD.
methodsData from the National Health and Nutrition Examination Survey (NHANES) spanning 2005-2018 was used in this study. Weighted logistic regressions, restricted cubic splines (RCS) were utilized to investigate the correlation between LE8 score and depression. Using a two-piecewise logistic regression model to identify potential threshold effects. Subgroups and sensitivity analyses were conducted to test the robust of the association.
resultsThe study encompassed a total of 1,110 subjects diagnosed with COPD. In fully adjusted statistical model, an increment of 10 points in the LE8 score was correlated with a reduced likelihood of depression (OR: 0.68, 95% CI: 0.58-0.78). Similar trends in the associations of health behavior score (OR = 0.75, 95% CI: 0.67-0.84) with depression was also identified. The threshold for the LE8 score was pinpointed at 50.0; surpassing this value, the probability of depression decreased by 8.0% for each additional point in the LE8 score (OR, 0.92; 95% CI: 0.88-0.95; P < 0.001). Furthermore, higher LE8 metric scores of physical activity, nicotine exposure and sleep health were associated with a lower prevalence of depression. The results of subgroup and sensitivity analyses were found to be consistent with the principal analysis.
conclusionsThere is a non-linear relationship between LE8 score and depression, with an inflection point of roughly 50.0. Adhering to a higher LE8 score (≥50.0) was correlated with lower odds of depression among COPD adults aged ≥ 40years.
