Associations of cumulative exposure and dynamic trajectories of the C-reactive protein-triglyceride-glucose index with incident stroke in middle-aged and older Chinese adults: a longitudinal analysis based on CHARLS

This study demonstrates that both cuCTI and CTI changes are associated with stroke risk in middle-aged and older adults, particularly for those with consistently high CTI levels, which are linked to a significantly increased stroke risk. Monitoring long-term CTI changes and maintaining relatively low levels may help prevent stroke in this population.
