WebThe hazard is essentially the instantaneous rate of your outcome event, conditional on having survived up to that moment in time. A hazard ratio of 1.034 for your biomarker, modelled correctly, implies a 1.034-fold increase in the hazard of the outcome. Collett (2003) Modelling survival data in medical research covers this.

We found an increasing trend in the occurrence of … 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 ).
