Test is over – the following Power Points
*To revisit the concept of absolute risk.To introduce and compare the relative risk and odds ratio as measures of association between an exposure and a disease.To calculate and interpret a relative risk in a cohort study. To calculate and interpret an odds ratio in a cohort study and in a case-control study and to describe when the odds ratio is a good estimate of the relative risk. To calculate and interpret an odds ratio in a matched-pairs case-control study.
*To calculate and interpret the attributable risk for the exposed group. To calculate and interpret the population attributable risk.To describe how attributable risk is used to estimate the potential for prevention.
*From Association to Causation, Association to Causal,Types of causal relationship, Specificity of the association an Observed Association Is Causal
*To review some possible biases in epidemiologic studies, including selection bias and information bias. To define confounding and to discuss possible ways to deal with confounding in the design and/or analysis of an observational (nonrandomized) study. To define interaction and to present a framework for detecting whether (and to what extent) two factors interact to influence the risk of a disease.
