Residual cholesterol inflammatory index and its prognostic role in mortality among individuals with cardiovascular–kidney–metabolic syndrome stages 0–3 based on U.S. and Chinese national cohorts

Key Points

• Mortality is significantly predicted by the residual cholesterol inflammatory index in CKM stages 0-3.
• The analysis emphasizes the importance of this index for assessment and intervention.
• Observational analysis across U.S. and Chinese national cohorts highlights critical findings.
• These results suggest that earlier interventions may reduce mortality risks effectively.
