Document Summary

Lecture 7: assessment of risk and benefit in. Only looking at a single dependant and independent variable in this course. Attributable risk or ar indicator which assesses difference in risk between groups. Control group (no risk factor) vs experimental group (risk factor) Risk ratio or rr which assesses relative risk between groups; it is a ratio of the risk in an exposed group to the risk in the unexposed group. The odds ratio, or or reflects the odds or likelihood of an event/disease. Related to risk ratio, but is more suitable when the risk of the disease or condition in a population is low. Estimate odds of outcome given a risk factor. Determine the risk associated with particular risk factors. Attributable risk as a % of those exposed an extension of the attributable risk as a proportion of those who were exposed.
