Which is a common randomization method used in clinical trials?

• A. Simple randomization
• B. Bias randomization
• C. Outcome-based randomization
• D. Conditional randomization

Answer: (A)

Simple randomization is a common method used in clinical trials to assign participants to different treatment groups. This technique ensures that each participant has an equal chance of being assigned to any of the treatment groups, thereby promoting the idea of fairness and reducing the potential for selection bias. By leveraging this method, researchers can achieve groups that are similar in key characteristics, helping to enhance the validity of the trial's outcomes. Simple randomization is straightforward and does not require complex algorithms or statistical considerations, making it easy to implement in most trial scenarios. It plays a crucial role in maintaining the integrity of clinical trials as it allows for unbiased comparisons between different interventions. The other methods mentioned—bias randomization, outcome-based randomization, and conditional randomization—are either not standard methods recognized in clinical trial methodology or have specific applications that might not be as widely employed as simple randomization. These alternative methods may introduce complexities or aren’t aimed at the straightforward randomness that simple randomization provides.
