Study Types Epidemiology

An epidemiologic investigation ⇒ etiology of disease. − Study hypothesis. ▷ A specific statement regarding the relationship between two variables: exposure and disease outcome. An epidemiologic study ⇒ test the hypothesis of association. 18. Types of Bias. ▫ Selection bias. ▫ Information bias. ▫ Confounding.

Systematic error results in incorrect estimate of the association between exposure and disease. • Great potential for bias in epidemiologic studies – little control over participants. • Role of bias must be evaluated for interpretation of study results. • Bias, unlike confounding cannot be statistically controlled. • Major types:.
