What is a potential outcome of not utilizing blinded studies?

• A. Increased recruitment of participants
• B. Development of a comprehensive safety plan
• C. Increased risk of bias in results
• D. Faster completion of the study

Answer: (C)

Utilizing blinded studies is critical in clinical research as it minimizes bias among participants and researchers, which can significantly alter study outcomes. When a study is not blinded, participants are aware of the treatment they are receiving, which may influence their behavior, reporting of results, or reactions. This awareness can introduce systematic biases, such as placebo effects or differential reporting of symptoms, leading to skewed data. For instance, a participant who knows they are receiving a treatment may have heightened expectations of benefit, while those aware of receiving a placebo might report adverse effects more readily. Similarly, researchers who are not blinded may unintentionally influence participants or interpret results through a biased lens, impacting the integrity and validity of the findings. Thus, without blinding, the study's results may not accurately reflect the true efficacy or safety of the intervention being tested, undermining the overall trustworthiness of the research conclusions.
