A Likelihood ratio for a given diagnostic test result compares the likelihood of that result in patients with disease to the likelihood of that result in patients without disease. The hazard rate thus describes the instantaneous rate of failure at time t and ignores the accumulation of hazard up to time t (unlike F(t) and S(t) ).

It has gained popularity as a tool in the area of root cause analysis and incident investigation. The hazard function, then, describes the relative likelihood of the event occurring at time t ( f(t) ), conditional on the subject's survival up to that time t ( S(t) ). Collider bias can have major effects. • However, in most studies patients tend to drop out, become lost to followup, move away, etc. Relative risk reduction talks about an event is the likelihood of the happening after the exposure to a risk variable when compared in the light of happening of the occurrence of the same event in a controlled or a reference group.
