WitrynaAbstract Floating absolute risks are an alternative way of presenting relative risk estimates for poly-chotomous risk factors. Instead of choosing one level of the risk factor as a reference category, each level is assigned a “floated ” variance which describes the uncertainty in risk without reference to another level.
