Hi I was given a case series of one surgical treatment to obtain a hazard ratio
the question is: does this operation have a low risk of revision?
however to my knowledge, I can not obtain a hazard ratio as I do not have another treatment to compare it too (then again we are talking about ratios ie comparing one treatment to another, therefore there must be a comparison group ie a control)
and my only solution is to provide a KM curve?
do you agree with this ?
