What is the key feature of Randomized Control Trials (RCTs)?

Participants are assigned to treatment groups based on the severity of their condition

Participants are allocated to different interventions based on their preferences

Participants are assigned to treatment groups based on their demographics

Participants are assigned to treatment groups in a random manner (correct)

What is the purpose of blinding in randomized control trials?

To ensure that participants are aware of the treatment they are receiving

To encourage participants to influence the study results consciously

To discourage researchers from influencing the study results

To reduce bias and prevent conscious or subconscious influences on the study results (correct)

What is the gold standard in evaluating the effectiveness or efficacy of interventions?

Matching participants to specific interventions based on their demographics

Observing the participants' preferences for interventions

Allowing participants to choose their own interventions

Randomly assigning participants to treatment and control groups (correct)
