Hello All,

As I am new to the endpoint studies, how can we calculate 90% CI for continuous variable in clinical endpoint studies?

As per my understanding, there are two ways. One is ±20 rule for the difference of means and 80-120% rule for ratio of means of un-transformed data. Based on this reference 90% CI Calculation

But as per OGD, the 90%CI should lies in 80-125% for un-transformed data. Please see the point no.21 in the OGD (see Clindamycin Phosphate).

This is me a lot. Please clarify.
