Sample Size Calculation Guide - Part 3: How to Calculate the Sample Size for an Independent Case-control Study

Abstract

In the previous educational articles, we explained how to calculate the sample size for a rate or a single proportion and how to calculate the sample size for an independent cohort study. In this article, we will explain how to calculate the sample size for an independent case-control study based on the odds ratios or two proportions representing the exposure rates in the case and the control groups.
