Dear Shri,

If you have a significant treatment effect, it just means that the test product and the reference product are statistically different. If the CI lies below 100, this means that the bioavailability of the test product is statistically lower than the reference product.

Statistically different doesn't mean that the difference has any clinical relevance, I mean that the difference may not have any impact on the patients taking the drug. That's why 90 % CI are calculated, and we are not just testing for treatment effect in the ANOVA. As long as your 90 % CI lies within the acceptance limits (usually 80-125), the products are still considered bioequivalent.
