Web3 jun. 2016 · The hazard ratio is the ratio of these two expected hazards: h 0 (t)exp (b 1a)/ h 0 (t)exp (b 1b) = exp(b 1(a-b)) which does not depend on time, t. Thus the hazard is …
WebA hazard ratio is a rate ratio. A rate is "events per unit time". Given that the Cox model specifies proportional hazards at all time points, a hazard ratio of 1.2 means that the rate … WebSimilarly a risk ratio of 0.25 is interpreted as the probability of an event with treatment being one-quarter of that without treatment. This may be expressed alternatively by saying that treatment decreases the risk of events by 100 × (1 –RR)% = 75%. This is known as the relative risk reduction (see also Chapter 12, Section 12.5.1 ).
