Sample Size Calculation Guide - Part 5: How to calculate the sample size for a superiority 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, and for a diagnostic test accuracy study. In this article, we explain how to calculate the sample size for a superiority clinical trial.
