When doctors and scientists want to test new medicines or treatments, they do something called a clinical trial. This is like a big experiment where they give some people the new medicine and some people a fake medicine called a placebo. They want to see if the new medicine works better than the placebo.
Monitoring in clinical trials means that they want to make sure that everything is safe and fair during the trial. They check on the people who are taking part in the trial to see if they're okay. They also make sure that everyone is following the rules and doing things the right way.
The doctors and scientists who are running the trial watch everything very carefully to make sure that no one is hurt and that the results are good. They might ask people questions about how they're feeling, or check their blood to see if everything is going okay. They might also check to make sure that the new medicine is working like it's supposed to.
Monitoring is really important in clinical trials because it helps us understand if new medicines or treatments are safe and effective. If something goes wrong, the doctors and scientists can make changes or stop the trial to keep people safe. And if the new medicine works better than the placebo, it might be approved for use by doctors all over the world!
