The best biometric design for a clinical trial is a double-blind trial comparing the drug against another drug, or placebo. This means that neither the doctor nor patient can tell which treatment the patient is on. To do this both treatments must look identical. Sometimes this is not possible, perhaps 1 drug is a pill, and one is a liquid.
In this case biometrics dictates that a double blind double dummy design is used. A dummy liquid is made up to look like the active liquid, and a dummy pill is made up to look like the active pill.
Patients then are given either the active pill and the dummy liquid, or the active liquid and the dummy pill.

What evidence could a food scientist produce t show that food treated with radiation is safe to eat?
The scientist should conduct what is scientifically known as a clinical trial. A clinical trial can be performed in various ways, but the best would be the double blind controlled trial. The researcher would split the test subjects in two groups. One group would receive a dud, for instance non-treated food while the other group would receive treated food. The people handling the food will not know which group receives the treated food and which doesn't. After a certain period of time, the researcher can then compare the two groups and try to find deviations between the two groups, for instance a increased risk of cancer.

How can you use the word synergism in a sentence?
The clinical trial studied the synergism between hormones and the prescription drugs. Adherents of religious synergism suggest that believers must cooperatively determine their own destiny.

What is a double dummy study?
A double dummy study is a technique in administering supplies in a clinical trial. It refers to a method of blinding wherein the placebo is administered to both treatment groups.
Which of the following is used to avoid bias in a clinical trial?
Double Blind Testing -
What is a blind clinical trial?
This strict type of clinical trial eliminates any possibility of bias. Neither the participant or the researcher knows if the treatment or a placebo has been administered.
Double dummy in blind clinical trials?
Double-Dummy A technique for retaining the blind when administering supplies in a clinical trial, when the two treatments cannot be made identical. Supplies are prepared for Treatment A (active and indistinguishable placebo) and for Treatment B (active and indistinguishable placebo). Subjects then take two sets of treatment; either A (active) and B (placebo), or A (placebo) and B (active). Difficulties in achieving the double-blind ideal can arise: the treatments may be of a completely different nature, for example, surgery and drug therapy; two drugs may have different formulations and, although they could be made indistinguishable by the use of capsules, changing the formulation might also change the pharmacokinetic and/or pharmacodynamic properties and hence require that bioequivalence of the formulations be established; the daily pattern of administration of two treatments may differ. One way of achieving double-blind conditions under these circumstances is to use a 'double-dummy' technique. This technique may sometimes force an administration scheme that is sufficiently unusual to influence adversely the motivation and compliance of the subjects. Ethical difficulties may also interfere with its use when, for example, it entails dummy operative procedures. Nevertheless, extensive efforts should be made to overcome these difficulties.
What is a triple-dummy clinical trial?
If treatments are classed as A, B and C, and say, for example, C is placebo, then during the trial, every patient will receive A at some point, B at some other point and also C at another time. Therefore each patient is 'dummy' to what they are receiving. It's a 'triple' dummy because there are 3 different treatments.
When is a double-blind study not possible?
A double blind surgery is not possible when the medical intervention a patient is getting cannot be kept from them, such as a surgery. Both the scientist and the participant in the trial know exactly what the participant is getting done in the trial.
What is partially blinded clinical trial?
A blind in a clinical trial means that one party doesn't know what is being tried. For example, if a scientist wants to check the efficacy of a drug, a blind in this case would means that the person who conducts the trial wouldn't know which is the drug and which is the placebo. This was a single blind trial. A double bling would imply that the scientist doesn't know which research group gets which component. The purpose of blinds is to not allow human expectations to project onto the results. If a scientist expects a certain result, he will somehow see it and so to remove the error that could be caused by such a misinterpretation, most trials are partially blinded. The results from such trials are said to be unbaised because they are reported as is.
What is clinical trial data services?
Clinical Trial Data Services (CTDS) are an organization that focus on clinical research. The organization also provide understanding about clinical trial processes, for example.
