  • Prospective population-based cohort study

Authors' conclusion

The study reports an association between LDL-C ≥4.9 mmol/L and ASCVD in a large cohort from Switzerland.

Study context

Exposure
Low-density lipoprotein cholesterol (LDL-C) ≥4.9 mmol/L vs <4.9 mmol/L
  • LDL-C ≥4.9 mmol/Ln = 291
Outcome
First-time ASCVD
Follow-up
Median 14.3 years
