About
About the course
Course content
Study design, measures of disease occurrence, measures of effect, intern validity, Directed acyclic graphs (DAGs), interpretation of multivariable models, causal inference, causal interaction and effect measure modification, screening, instrumental variable estimation, family designs, case only designs.
Learning outcome
After completing SMED8002:
Knowledge
- The candidate is at the forefront of knowledge regarding various study designs most commonly used in population-based and clinical research (cross-sectional studies, cohort studies, case-control studies, and randomized controlled trials).
- The candidate can assess the appropriateness of different measures of disease occurrence (prevalence, incidence rate, and incidence proportion) and screening.
Skills
- The candidate can handle and interpret various complex measures of the relationship between exposure/treatment and disease based on absolute and relative risk (risk difference, incidence rate difference, numbers needed to treat versus risk ratio, incidence rate ratio, odds ratio, hazard ratio).
- The candidate can distinguish between and understand the concepts of ‘causal relationship’ (causality) and ‘statistical association’.
- The candidate can differentiate between causal interaction and effect measure modification.
General proficiency
- The candidate has in-depth knowledge of common challenges in observational studies (selection bias, information bias, and confounding).
- The candidate has in-depth knowledge of interpreting Directed Acyclic Graphs (DAGs).
- The candidate has in-depth knowledge of assessing precision in epidemiological studies with an emphasis on the interpretation and use of p-values and confidence intervals.
- The candidate has a thorough understanding of the principles of multivariable analyses and the ability to interpret such analyses.
- The candidate has in-depth knowledge of the principles of instrumental variable analysis, various family designs, and case-only studies.
Learning methods and activities
Teaching modalities: Lectures and problem solving. Participation is mandatory. The course coordinator may approve up to 20% absence from mandatory lectures.
Compulsory assignments
- Practice tasks
- Mandatory attendance at lectures
Further on evaluation
The lectures for the course are organized into two separate teaching weeks. The first week is usually in March, while the second week is four weeks after the first teaching week. Each day during the teaching weeks is divided into two parts, with lectures in one half of the day and group exercises in the other half. Attendance at lectures and exercises is mandatory, but it is possible to apply for approved absences upon evaluation.
Recommended previous knowledge
KLMED8004 Medical statistics 1, KLMED8009 Clinical Research, introductory course in epidemiology (e.g. master course in epidemiology)
Required previous knowledge
Master's degree. Medical students at The Student Research Programme.
