Which is better?. Guideline eligibility or RCT eligibility Copenhagen General Population Study (CGPS).
Research Gap. CPBS Homogenous source population All participants had health insurance Race and ethnicity are determinates of dyslipidemia as well as a risk factor for CVD.
Project Proposal. Evaluation of Guideline and Trial Based Approaches for Statin Use as an Effective Primary Prevention Strategy- A Proposal for a Prospective Cohort Study in the United States.
Methods. Source Population Kaiser Permanente Exposures RCT eligibility Outcomes ASCVD events.
Statistical Analysis. examine the extent to which RCT evidence supports each of guideline-based recommendations examine RCTs demonstrating statin efficacy for persons in different guidelines-based risk groups Evaluate clinical performance of the guidelines- and RCT approaches Incidence rate s & hazard rations with 95% CI estimate the number needed to treat (NNT) to avert one instance of ASCVD in 10 years, stratified by guideline- and RCT eligibility groups.
Strengths and Limitations. unable to account for preventative drug use, such as statins, during follow-up, which could influence the incidence of ASCVD participant’s baseline characteristics may change over time -> misclassification Long follow-up period Susceptible to non-response bias.
