Abstract:
|
One important aspect in the design of clinical studies is to determine the sample size such that there is sufficient power in detecting clinically meaningful treatment effect. A pilot study can help in estimating the variability of the outcome to provide realistic parameters in the design of main studies. In this paper, we present a method to calculate the sample size for the pilot study, such that the power calculation in the main will be realistic with adequate performance. We derive the pilot study sample size formula according to the desired performance of the main study and using simulations to demonstrate the performance of this method.
