While RCTs are highly regarded, they are not without limitations. Some of these include:
Cost: RCTs can be expensive and time-consuming to conduct. Generalizability: The highly controlled conditions of RCTs may not reflect real-world settings, limiting the generalizability of the findings. Ethical Constraints: In some cases, it may be unethical to withhold a potentially beneficial treatment or to expose participants to certain risks. Complexity: Designing and implementing RCTs can be complex, requiring meticulous planning and execution.
