A comprehensive introduction to key concepts for observational (non-randomised) studies in clinical and public health research.

Observational studies are central to modern health research. They are key to addressing descriptive and predictive research questions, to quantify disease burden and enable risk stratification. Observational studies are also widely used to address "causal" questions, about the effect of treatments, policies, behaviours and other exposures on health outcomes.

Course overview

This course reviews the distinction between the three types of research questions (descriptive, predictive, and causal) and then provides a comprehensive introduction to causal inference and a guide to using regression to address causal questions.

An overview of key concepts in the study of descriptive and predictive questions is also provided. The course has a strong emphasis on the design and planning of analyses – a critical step to strengthen the quality of conclusions we draw from these studies.

Please note: CEBU offers a core sequence of research methods courses. It is strongly recommended that the three courses: Designing Your Research StudyIntroduction to Biostatistics and Observational Studies be taken in that sequence because the latter ones assume familiarity with concepts, language and techniques introduced in the earlier ones. This course is third in the sequence and is not entry-level.

University of Melbourne
This course is delivered by Clinical Epidemiology and Biostatistics Unit (CEBU), a working partnership between Murdoch Children's Research Institute and the University of Melbourne.

Course format

Topics covered in the Observational Studies: Modern concepts & analytic methods course include:

  • The three types of research questions
  • Definition of causal effects using the target trial framework
  • Causal diagrams
  • Biases: confounding bias, selection bias, measurement error bias
  • Analysis planning for causal inference (target trial emulation)
  • Review causal effect measures (mean difference, risk difference, risk ratio, etc)
  • Basic concepts of regression and overview of different types of regression (linear, logistic, log-binomial)
  • Regression as a method for estimating causal effects
  • Interpretation and reporting of regression results
  • Interaction terms in regression
  • A brief introduction to causal inference methods beyond regression
