Institutional Review Board is an independent committee responsible for reviewing and approving clinical trial

In a double-blind trial, neither the participants nor the researchers know who receives the experimental treatment and who gets the placebo

In a placebo-controlled trial, some participants receive a placebo (inactive treatment) while others receive the experimental treatment.

Protocol is a detailed plan that outlines the objectives, design, methodology, and ethical considerations of a clinical trial.

The Principal Investigator (PI) is the lead researcher responsible for conducting the clinical trial.

Adverse events are more severe and unexpected reactions, which are closely monitored and reported during a trial.

A control group in a clinical trial is a group of participants who do not receive the experimental treatment.

Randomization is the process of randomly assigning participants to different groups in a clinical trial.

Blinding means participants or researchers may not know who receives the placebo to minimize bias.

Informed consent is the process where participants receive detailed information about the clinical trial, including its purpose
