WebDefinition of risk ratio. A risk ratio (RR), also called relative risk, compares the risk of a health event (disease, injury, risk factor, or death) among one group with the risk among another group. It does so by dividing the risk (incidence proportion, attack rate) in group 1 by the risk (incidence proportion, attack rate) in group 2. WebCumulative probabilities for an interval are calculated by multiplying the interval survival rates up to that interval. For example, the chances of survival begin in interval one as 6/6, then are 5/6 in interval two, and 4/5 for interval three giving a cumulative survival rate (probability) in interval three of 6/6 × 5/6 × 4/5 = 0.667.

WebCumulative incidence graphs show the opposite relationship, providing the probability that the event of interest HAS occurred by a given time “t”. This can be mathematically described as being 1 - survival …
WebWhat we mean by "survival" in this context is remaining free of a particular outcome over time. ... Cumulative incidence, or cumulative failure probability, is computed as 1-S t and can be computed easily from the life table using the Kaplan-Meier approach.
