Dr. Lucas explains the methodology of prospective and retrospective cohort studies, relative risk calculations, and how to minimize methodological biases.

In this session, Dr. Lucas walks us through cohort studies, explaining how prospective and retrospective cohorts work, how to calculate and interpret relative risk (RR), how risk calculators (like the Framingham Risk Score) are built, and how to identify and minimize key methodological biases. This series is a pilot project developed by the Cochrane Early Career Professionals Network, designed to introduce undergraduate students, early-career researchers, and healthcare professionals to core principles of evidence-based healthcare. In this session, you'll learn: • What defines a cohort study design and its core methodology • The key differences between prospective and retrospective cohort studies • How cohort studies differ fundamentally from case-control studies. • Calculating measures of disease frequency and relative risk • Real-world applications: using cohort data for clinical risk prediction tools • Identifying critical biases in cohort studies: confounding factors, surveillance bias, loss to follow-up, and inadequate follow-up time. • Critical appraisal tools for evaluating cohort studies ⏱️Timestamps: - Introduction & overview of the Cochrane Early Career Professional Network - Speaker introduction & session objectives - Clinical vignette: estimating cardiovascular risk in primary care - Risk calculators & The Framingham heart study - Cohorts in action: The ELSA-Brasil study - What is a cohort study?
