Understanding Randomized Control Trials

What is the primary purpose of a Randomized Control Trial in clinical research?

• To compare a new treatment against a standard or placebo

• To evaluate patient satisfaction with treatments

• To determine the cost-effectiveness of treatments

• To test the safety of new drugs

Why is it crucial for the treatment and control groups in an RCT to be similar before the intervention?

• To attribute any differences to the treatment rather than pre-existing differences

• To increase the number of participants

• To ensure the study is completed on time

• To make the study more cost-effective

What is the main advantage of a double-blinded study?

• It speeds up the data collection process

• It reduces the cost of the study

• It ensures participants receive the correct treatment

• It prevents bias from both participants and investigators

What is the role of blinding in a study?

• To eliminate bias from expectations

• To increase the number of participants

• To ensure the study is completed faster

• To reduce the cost of the study

Besides drug testing, what other areas can RCTs be applied to?

• In determining treatment costs

• In evaluating patient satisfaction

• In comparing devices or diagnostic procedures

• Only in drug testing
