Positive outcome trials driven by reduction in nonfatal myocardial infarction: A systematic review and relevant guideline recommendations
Authors' conclusion
In contemporary pharmacological RCTs with positive composite outcome driven by nonfatal MI reduction, intensive lipid-lowering trials are more frequently received strong guideline recommendations.
Study context
- Population
- Pharmacological randomized controlled trials (RCTs) published 2000–2024 with positive outcomes driven by nonfatal myocardial infarction (MI) reduction, cited in current guidelinesRCTs, of 21,005 records
- Participants
- 6 rcts
- Comparison
- Guideline recommendation classes for positive RCTs driven by nonfatal MI reduction, by therapy class
- Intensive lipid-loweringn = 2
- Anti-thromboticn = 3
- Anti-inflammatoryn = 1
- Outcome
- Guideline recommendation class by therapy type of trials with positive outcomes driven by nonfatal MI reduction
