• Part2: Clinical trials: different phases and sampling (professionals outcomes)
• Part3: diagnostic tests from the biological and statistical point of view ( sensibility, specificity, predictive values, ROC curves ) with exercises with Excel or Past
• Part4: basis of epidemiology ( definition of differences between cause and risk, introduction to the main indicators used in epidemiology, such as odds ratio and relative risk ratio), survival curves and their analysis

## Teaching methods

Frontal lectures, practise exercises on the PC, discussion of scientific papers given by the lecturer

## Assessment methods and criteria

At the end of the course each student will receive a written exam to prepare at home, and that will be discussed in detail orally.
With respect to the Dublin’s descriptors, it will be evaluated:
• knowledge and comprehension of the topics discussed in the classroom, considering also the use of text books
• the capacity to apply the acquired knowledge to case studies, where of critical importance will be the capacity to collect data, to interpret them, and to communicate them in a clear and critical way
