Epidemiologic methods: the "art" in the state of the art

@article{citeulike:2808834, abstract = {When performing empirical research in public health and medicine, the investigator is typically faced with a variety of methodologic issues to resolve at the design and analysis stages of the research. The investigator must specify the research question, conceptualize and operationalize the variables to be measured, consider several research designs to choose from, determine appropriate measures of disease frequency and effect, address potential biases, devise the analytic strategies to follow, choose the appropriate software procedures or packages to use, carry out the analysis, and interpret the results. Most of these issues concern principles and methods of epidemiology and biostatistics, which, taken together, embody the methodologic "science" that underlies such research.
