Content of the course
The course includes the following four blocks:
1. Design and analysis of studies with a focus on binary outcomes
• Cohort and case-control studies
• Incidence and risk measures
• Measures of association: Odds ratio, absolute and relative associations
• Basic survival problems (time-to-event)
2. Introduction to correlation- and regression analysis
• Spearman’s and Pearson’s correlation coefficients
• Simple linear regression
• Simple logistic regression
3. Regression analysis - advanced
• Introduction to Cox regression
• Multivariable modelling
4. Randomized Controlled Trials (RCT) and diagnostic studies
• Design and analysis of randomized controlled trials
• Diagnostic measures: sensitivity, specificity, predictive values
This course for clinical researchers focuses on regression methods, especially linear regression models for a continuous outcome variable and one or more independent variables: in what situations they can be used and how the results should be interpreted.
The course will also cover how regression methods can be used to assess and handle confounding and interaction. Further, other types of regression models such as for binary outcomes (logistic regression) and survival analysis (Cox regression) will be introduced. Additionally, statistical methods for diagnostic tests will be covered by introducing sensitivity, specificity, positive and negative predictive value, as well as choice of cut off with ROC-analysis. The course also introduces theory and regulations around randomized controlled trials.
