Statistical Methods in Epidemiology (3 or 7 credits)
Contents: The course explains concepts, study designs and statistical models needed to estimate the incidence and prevalence of a given disease or, more generally, some healthrelated event and its association with possible exposure variables. The course will cover prospective (cohort) and retrospective (casecontrol) study designs. The first part of the course (3 cr) is taught as an intensive course and introduces the concepts and statistical models at a fairly general level. The second part (4 cr) focuses in more detail on use and interpretation of the main regression models in epidemiology. The course will be lectured in English.
To whom is the course targeted?

The first of the part suits to all those who need to analyse or interpret epidemiological data and research findings in medicine, epidemiology, public health or related fields. Some former knowledge of statistical methods is beneficial but not absolutely necessary.

The second part introduces the main types of regression models used to analyse epidemiological data. For students majoring in statistics, the course is recommended during the 3^{rd} year studies. These students are expected to successfully complete both parts of the course to gain a total of 7 cr. For students not majoring in statistics, the second part of the course is optional.
Aims

Part I: to familiarise with the basic epidemiological concepts (risk, odds, hazard, relative risk, persontime, confounding etc.) & to learn to explore and summarise epidemiological data.

Part II: to learn to analyse populationbased epidemiological data using Poisson and logistic regression & to interpret epidemiological research papers.
