I wanted to comment on a concept that is used a lot in engineering but I have not seen it much in medicine, the elasticity of time to the event.
What I thought I knew before I read this was that the hazard rate is a rate of events per unit of time.
Therefore, the reciprocal (1/ hazard rate) is the average time in which the events occur.
Now, I have seen RCTs in which 100/HR is interpreted similarly to a “time ratio”, as the ratio of the average time to the event for the two levels of the variable.
I wanted to ask why this elastic function of engineers is not popular in medicine.
