Clinical Practice in NI studies

Prof. Mary Ferrill gives three examples to make sure that we are able to apply the knowledge on studies.

She starts this video with three questions.

Can superiority be concluded from an NI study? Can NI be assumed if a superiority study was not significant? Can the authors try to prove NI posthoc after nonsignificant results are concluded in a superiority study?

Besides, we are given three cases to verify our ideas.

In the second case, we can see that it doesn’t meet non-inferiority. However, if you look at their results, they have been listed. Why would this happen?

Please watch this video and share your answers for the above questions.
