Authors' conclusion

An elevated AIP in a community-based population is associated with a higher rate of CA. the AIP could serve as a potential biomarker for CA risk assessment.

Study context

Population
Community residents aged ≥40 years who underwent cervical vascular US, December 2017 to December 2020, Hunan, China
Participants
52,380 residents
Exposure
Atherogenic index of plasma (AIP) quartiles and per 1-SD increase in AIP
Outcome
Carotid atherosclerosis (CA), increased carotid intima-media thickness (CIMT), plaques and stenosis
Methodological detailspopulation-based, community-based
  • Population-based
  • Community-based

Further findings

Subgroup analyses

More significant association between AIP and carotid atherosclerosis (CA) in younger subjects (aged < 60 years) with body mass index (BMI) ≥ 24 and fewer comorbidities

Incremental predictive value for CA over established risk factors

Improvement in net reclassification index (NRI) and integrated discrimination index (IDI)
all P < 0.05
