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

backgroundCardiovascular-kidney-metabolic (CKM) syndrome, integrating cardiovascular disease (CVD), chronic kidney disease (CKD), and metabolic dysfunction, is a construct proposed by the American heart association. Although associations with CVD are well recognized, evidence linking CKM stage to renal outcomes remains limited.

methodsWe analyzed health checkup data of 266,256 Japanese aged 40-74 years. Participants were classified into CKM stages 0-4a. Outcomes included all-cause mortality, cardiovascular death, and a composite renal outcome (end-stage kidney disease [eGFR < 15 mL/min/1.73 m

resultsCKM stage 2 was the most prevalent stage (65.0%). Stage 4a showed the strongest association with all-cause and cardiovascular mortality (HRs 1.79, 3.16; 95% CIs 1.41-2.28, 1.92-5.20, respectively). In contrast, stage 3 conferred the highest risk of renal outcomes (HR 15.29, 95% CI 10.13-23.08). The number and type of metabolic risk factors correlated with outcomes, furthermore, severe CKD and prior CVD were stronger drivers of adverse outcomes than metabolic dysfunction.

conclusionCKM staging stratifies risk in the general population. No significant increase in risk was observed until CKM stage 2, and these findings underscore the progressive, cumulative nature of CKM syndrome. Metabolic dysfunction plays a crucial role in progression, stage 3 marks a pivotal inflection point for renal deterioration, and stage 4a identifies individuals at the greatest mortality risk. Early interventions targeting metabolic dysfunction may help prevent progression to advanced CKM stages and improve long-term outcomes.
