RegisterTwo Tests with Same Reference [Design Issues]
Dear Noha,
Yes I just finished running a 3 test vs 1 reference submission. FDA ok'd.
This the part you need to be aware of --> Common Variance. Refer to a discussion I had with Helmut and folks here a few months. There is a potential danger if the product (or products) barely passes the 90% CI.
3-way study.
