Registercalculation of 90% CI for continuous variable in clinical endpoint studies [General Statistics]
Hi GM,
the tradition is to use 80.00%-125.00% for a ratio of continuous variables. This makes extremely good sense under a certain set of assumptions.
You refer to section 21 of the guidance, but this does not relate to continuous variables. It applies to dichotomous variables instead.
Rule of thumb: For a difference, the acceptance range is symmetric. For a ratio the lower acceptance limit equals the reciprocal upper limit, naturally. Most BE issues you will come across have elements of both if logs are involved.
