# Multiplicity Problems in the Clinical Trial and Some Statistical Approaches

Conference paper

## Summary

In a clinical trial there arise a variety of multiplicity problems which might cause the bias and need to be considered carefully in analyzing and interpreting the data. We first introduce those problems frequently encountered in practice and then discuss some statistical approaches to overcome the difficulty.
