Why is a placebo group included in clinical trials?
sometimes just taking a pill will make people think they are getting better when they really aren't. when you include a placebo group, you can take away the percent that thought they were getting better from the group that was taking the real pills to get a more realistic answer of how the pills are making people feel.
Do contraceptive pills work if you don't believe in them.. Any evidence from clinical trials with a placebo group. Reason I ask is that clinical trials have proven that placebos work for pain reliev?
Birth control pills are quite reliable. They are made with hormones that do change what happens inside a woman's body, regardless of what she may or may not believe. They do not depend upon the placebo effect.
Is nicotine patch and placebo the same?
No. A placebo is in a way a "fake medication", a pill without the active ingredient. Often used in clinical trials for the "control group", to avoid psychological bias. A nicotine patch does have an active ingredient (the nicotine), and is used to gradually wean people of smoking.
Explain the relationship between a placebo and a control?
A placebo is a substance or treatment that has no therapeutic effect, used in clinical trials to test the effectiveness of a real intervention. A control group is a group in the study that does not receive the treatment being tested, used to compare the effects of the treatment against no treatment. In a clinical trial, the control group may receive a placebo to help ensure that any observed effects are due to the treatment being tested and not to other factors.
What does intervention or clinical trials mean?
Clinical trials are controlled and paid experiments using humans as subjects. The clinical trials may consists of taking medicines or administration of it to an informed individual or group of informed individuals. The results from these trials are used for the improvement of certain treatment modalities or how to control a specific illness.
What is scientific evidence?
Well that is a vague question, but in medicine there needs to have been clinical trials that prove that a particular drug works. Studies need to be done comparing the drug in question against a placebo. One group will receive the drug and another will receive the placebo. If the drug works, there should be significant number of patients who obtain the desired results.

Give two reasons why clinical trials have to be done before drugs are made freely available?
There are many reasons why clinical trials need to be conducted before making new drugs commercially available. First of all, drug makers need to be sure that a drug is safe, this is tested by giving the drug to a group of volunteers in a controlled environment (staying at a clinic for several days) and monitoring their vital signs, their blood chemistry, and checking for any side effects. Secondly, clinical trials are needed to determine whether a drug is effective at treating a certain condition. Drugs in clinical trials are given blind, meaning that the doctor nor the patient knows whether someone is taking the drug being studied or a placebo (sugar pill). Studying the effects of the drug in this scenario can prove whether the drug is effective. Finally, clinical trials are also used to determine the proper dose of a drug by giving escalating doses to volunteers and monitoring the blood levels of the drug and watching for any side effects.

What is a placebo used for in scientific studies?
Placebo is a dummy drug, which is identical in appearance to the drug under study but will have no therapeutic property. Placebos are used in clinical trials in order compare the effect of drugs on humans. The placebos are given to the control group and the drug is given to the treatment group. The effects on both the groups are then documented and compared to see the action of the drug in humans. Placebos are used in randomized, controlled trials.
