Sample Size Calculation Guide - Part 6: How to calculate the sample size for a non-inferiority or an equivalence clinical trial
Abstract
In the previous educational articles, we explained how to calculate the sample size for a rate or a single proportion, for an independent cohort study, for an independent case-control study, for a diagnostic test accuracy study, and for a superiority clinical trial. In this article, we will explain how to calculate the sample size for a non-inferiority or equivalence clinical trial.
