Association between physical activity and cardiovascular-kidney-metabolic syndrome in older Chinese adults: a nationwide, 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
Background: Cardiovascular-kidney-metabolic (CKM) syndrome represents a new framework to address the non-communicable disease burden in ageing populations. However, evidence on the association between physical activity and the integrated CKM syndrome is scarce, particularly among older Asian adults. We aimed to investigate this association in a large sample of older Chinese adults. Methods: This cross-sectional study utilised data from the China Ageing and Health Survey, including 41 829 community-dwelling adults aged ≥65 years. Physical activity was assessed using the validated Physical Activity Scale for the Elderly (PASE). Cardiovascular-kidney-metabolic syndrome was defined based on the 2023 American Heart Association criteria (Stages 1-4 vs. Stage 0). Multivariable logistic regression models were used to examine the association between PASE quartiles and CKM syndrome prevalence. Results: The prevalence of CKM syndrome was 80.3%. After full adjustment, a significant inverse dose-response relationship was observed between physical activity and CKM syndrome (P for trend <0.001). Participants in the highest physical activity quartile had 21% lower odds of CKM syndrome compared to the lowest quartile (adjusted odds ratio (aOR) = 0.79; 95% CI = 0.74-0.85). This inverse association was consistent across sexes but was strongly age-dependent: it was most pronounced among individuals aged ≥80 years (P for trend <0.001) and non-significant in the 65-69 age group (P for trend >0.05). Conclusions: Higher physical activity is independently associated with a lower prevalence of CKM syndrome in older Chinese adults. This inverse association was strikingly age-dependent and most pronounced in the oldest-old (aged ≥80 years). For aging populations globally, promoting accessible, age-appropriate physical activity may represent a high-priority, low-cost public health strategy to reduce CKM burden, particularly in this most vulnerable demographic.
