Epidemiology
IEA(2014), A dictionary of Epidemiology, 6th edition by Miquel Porta, Oxford

6. Study Designs
Choosing the appropriate study
design is a crucial step in an
epidemiological investigation.
Each study design has
strengths and weaknesses,
influencing the type of
questions they can answer and
the strength of evidence they
provide.
