Association between Cardiovascular-Kidney-Metabolic Syndrome and Depressive Symptoms in Middle-Aged and Older Chinese Adults: A Cross-Sectional and Longitudinal Analysis.

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
introductionCardiovascular-kidney-metabolic (CKM) syndrome and depressive disorder represent major public health burdens. While associations between depression and individual components of CKM syndrome have been established, the relationship between depression and CKM syndrome as an integrated clinical construct remains poorly understood.
methodsData from the China Health and Retirement Longitudinal Study (CHARLS) were used, including 8,088 participants in cross-sectional analyses and 1,803 in longitudinal analyses. CKM syndrome was classified according to the American Heart Association (AHA) staging criteria, and depressive symptoms were assessed using the 10-item Center for Epidemiologic Studies Depression Scale (CES-D-10). The association between CKM stage and depressive symptoms was evaluated using ordinary least squares regression models with five levels of covariate adjustment. Subgroup analyses and interaction tests were conducted to investigate interaction effects across different populations.
resultsHigher CKM stages were significantly associated with increased depressive symptom severity. In the cross-sectional analysis (2011), mean CES-D-10 scores were 8.6 ± 6.4, 8.6 ± 6.3, 8.1 ± 6.2, and 10.7 ± 6.9 for the total population and CKM stages 0-1, 2-3, and 4, respectively. Scores in stage 4 exceeded the threshold for severe depressive symptoms and were significantly higher than those in other stages (p < 0.001). Subgroup analyses further confirmed the robustness of these findings. In longitudinal analyses, progression in CKM stage over a 4-year period was independently associated with an increase in CES-D-10 scores in the fully adjusted model (β = 0.31, 95% CI: 0.07-0.54).
conclusionsCKM syndrome is significantly associated with depressive symptoms, especially in stage 4. There is a positive relationship between CKM progression and depressive symptom severity, highlighting the need for integrated physical and mental health care for CKM patients.
