1 · What the graph read from it

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.

2 · The registry

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

backgroundCardio-kidney-metabolic (CKM) syndrome is a complex, multi-system health condition that affects aging populations, potentially contributing to frailty. This study aimed to examine the association between baseline CKM syndrome, its transitions over time, and the onset of frailty, using data from the China Health and Retirement Longitudinal Study (CHARLS).

methodsData from 11,031 participants in the 2011 baseline and 7454 individuals with follow-up data from 2015 were analyzed. CKM syndrome was categorized into five stages based on metabolic, renal, and cardiovascular dysfunction. Frailty was assessed using a 32-item frailty index (FI), with participants categorized as frail (FI ≥ 0.25) or non-frail (FI < 0.25). Logistic regression models were used to investigate the associations between CKM stages, transitions, and frailty risk, adjusting for potential confounders.

resultsOur findings revealed that participants in advanced stages of CKM (Stages 3-4) exhibited a significantly increased risk of frailty, with adjusted odds ratios of 1.97 (95% CI 1.29-3.01) and 4.45 (95% CI 2.83-7.00), respectively. Of particular note, 30.23% of participants experienced progression to more severe CKM stages during the study duration, while only 10.66% displayed improvement, further emphasizing the chronic nature of the syndrome. Logistic regression indicated that frailty risk was significantly associated with CKM stage transitions, particularly for those moving from stages 0 to 1.

conclusionsBoth baseline severity and progression of CKM syndrome are independently associated with a higher risk of frailty development. Early identification and intervention in CKM may help mitigate frailty risk in later life.
