Statistical power and sample size calculations: A primer for pediatric surgeons

Determining the appropriate sample size is an integral component of any well-designed research study, grant application, or scientific manuscript. Surgeons intuitively understand the concept of statistical power, but have limited knowledge in how to go about performing the calculations correctly. Our goal is to provide a strategy for pediatric surgeons to use when planning a study to determine the sample sizes required for detecting a clinically meaningful effect, which is important for interpreting and validating their results.
