Sample Size Calculation Guide - Part 7: How to Calculate the Sample Size Based on a Correlation.
INTRODUCTION 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, for a superiority clinical trial, and for a non-inferiority or equivalence clinical trial (1-6). In this article, we will explain how to calculate the sample size for a clinical study with the aim of detecting the correlation coefficient between two variables.
