Calculator Sample Size Non Inferiority. If an appropriate margin has been chosen a confidence interval that lies entirely between and 0. Here a type- I error occurs when you falsely conclude non-inferiority.
Here a type- I error occurs when you falsely conclude non-inferiority. This calculator is designed for binary outcomes in parallel group non-inferiority trials. A small study is not a justification for a wider non-inferiority margin.
The mean outcome is compared between the experimental and standard treatment groups.
Effect Size Differences D0 Non-Inferiority Difference. This calculator is designed for continuous outcomes such as walking distance blood pressure white blood cell count in parallel group non-inferiority trials. 2-Sample Non-Inferiority or Superiority. However only large sample normal approximation results are given there.
