The effect of fibrates on lowering low-density lipoprotein cholesterol and cardiovascular risk reduction: a systemic review and meta-analysis

Eur J Prev CardiolPublished

  • Systematic review and meta-analysis of randomised trials
  • prespecified meta-regression

Authors' conclusion

Treatment with fibrates was associated with decreased risk of MACE. The reduction in MACE risk with fibrate therapy appears to be attributable to LDL-C reduction rather than a decrease in triglyceride levels.
