Statistics for hospital epidemiology. General design and analysis questions.
In this first article of the series, we have listed a number of issues for the design and analysis of epidemiologic studies. In subsequent papers, we shall discuss methods appropriate for a variety of data from both retrospective and prospective studies. Methods of analysis will be described that will permit adequate control for stratification variables and adjustment for factors related to both disease and risk factor. When possible, we shall describe computer packages that will be helpful in carrying out the analysis. Our emphasis, however, will be on interpretation of the methods we describe.
