Hazard ratio to relative risk
WebbThe relative risk (also known as the risk ratio or prevalence ratio) is the ratio of event probabilities at two levels of a variable or two settings of the predictors in a model, where the "event" is the response level of interest. The relative risk can be estimated in the context of a model or using a nonmodeling approach. WebbRealRisk works with any study which investigates the link between a risk factor or intervention and an outcome of interest, which also reports one of the following: a relative risk (RR), hazard ratio (HR), odds ratio (OR) or a percentage change.. The study can be observational or experimental in design. The terminology used can vary – so don’t be put …
