The risk difference (RD), excess risk, or attributable risk is the difference between the risk of an outcome in the exposed group and the unexposed group. It is computed as , where is the incidence in the exposed group, and is the incidence in the unexposed group. If the risk of an outcome is increased by the exposure, the term absolute risk increase (ARI) is used, and computed as .

WebA standard deviation of 1 may be high or low – it depends on the data set and its mean. For a data set with a mean of 100 and a standard deviation of 1, the coefficient of variation is: CV = S/M = 1/100 = 0.01 This coefficient of variation is far less than 1, so a standard deviation of 1 is low in this case. WebHazard ratios are measures of association widely used in prospective studies (see later). It is the result of comparing the hazard function among exposed to the hazard function among non-exposed. As for the other measures of association, a hazard ratio of 1 means lack of association, a hazard ratio greater than 1 suggests an increased risk, and ...
