WEBDec 12, 2017 · In a superiority trial, we want to show that the new treatment intervention (drug, psychotherapy) is superior to (better than) the control condition.

WEBPMID: 18537788. Abstract. When the aim of the randomized controlled trial (RCT) is to show that one treatment is superior to another, a statistical test is employed and the trial (test) is called a superiority trial (test). Often a nonsignificant superiority test is wrongly interpreted as proof of no difference between the two treatments.

WEBJan 1, 2011 · The superiority comparison is a subset of the non-inferiority and will have a sample size that is similar to the non-inferiority or a sample size that is much larger. As the expected difference between the two treatments decreases, the sample size will increase, often dramatically.
