TY - CHAP M1 - Book, Section TI - Epidemiology: Measuring Risk A1 - Portney, Leslie G. A1 - Watkins, Mary P. PY - 2017 T2 - Foundations of Clinical Research: Applications to Practice, 3e AB - Throughout this text, we have addressed the importance of understanding basic elements of research design and statistics for clinical decision making, especially within the context of evidence-based practice. In this chapter we will present an important perspective in health care research based on principles of epidemiology. The information from epidemiological research can have direct influence on practitioners' day-to-day choices related to diagnosis, prognosis or intervention. The purpose of this chapter is to present statistical methods for measures of disease frequency, estimates of health risks for cohort and case-control studies, and the evaluation of treatment effects in randomized trials.
