Delete randomization window
The randomization window is a predefined timeframe within which subjects can be enrolled and assigned to their respective treatment groups. Its purpose is to ensure the random and unbiased allocation of subjects, thereby enhancing the scientific validity of the research. The duration of the randomization window and its criteria can vary depending on the study protocol and design.
The created randomization window affects the randomization process in IWRS as it defines the start and end dates during which subjects can be enrolled and assigned to treatment groups. A randomization window can be deleted if no longer required due to new study requirements.
