Interim Analysis

Interim analysis is a planned review of data collected during a clinical trial before it is fully completed. It allows researchers to evaluate if a treatment is working, is safe, or if the trial should be stopped early for ethical reasons. This process helps ensure patient safety and can save time and resources by stopping ineffective or harmful studies sooner. However, conducting interim analysis requires careful planning to prevent bias or false conclusions. It is an essential part of clinical research to make informed decisions and maintain trial integrity.
