During the clinical trial, all patients are given both placebo and active doses in alternating periods of time.
A common mistake in a clinical trial is failure to carefully examine the literature for similar, prior research. Also failure to critically assess the prior literature. Another mistake is failure to specify the inclusion and exclusion criteria for your subjects.

To the best of my knowledge: A clinical assessment would include a diagnosis, and a non-clinical assessment would have a plan of action.
Clinical trial is any research study that prospectively assigns human participants or groups of humans to one or more health-related involvement to evaluate the effects on health outcomes. Clinical research trials may be conducted by government health agencies such as NIH (National Institute of Health), researchers affiliated with a hospital or university medical program, independent researchers, or private industry. Clinical trial interventions include but are not restricted to: Experimental Drugs Cells and Other Biological Products Vaccines Medical Devices Surgical and Other Medical Treatments and Procedures Psychotherapeutic and Behavioural Therapies Health Service Changes Preventive Care Strategies and Educational Interventions. Researchers may also conduct clinical trials to evaluate diagnostic or screening tests and new ways to detect and treat disease. Types of Clinical TrialsThere are two main types of clinical trials: Observational clinical trials do not test drugs or treatments. Researchers observe participants by monitoring their health over a period of time. These studies provide researchers with data that advances our understanding of Parkinson’s and how to treat the disease. Interventional clinical trials test the safety and effectiveness of a candidate drug, therapy or experimental treatment. Clinical trials also can be classified as follows: Treatment trials Prevention trials Screening trials Quality of Life trials Genetics trials Phases in Clinical Trials: Phase 0: Number of Subjects (10-15) Phase I: Screening for safety: Number of Subjects (20-80) Phase II: preliminary efficacy of the drug: Number of Subjects (100-300) Phase III: Final confirmation of safety and efficacy: Number of Subjects (1000-3000) Phase IV: Post marketing studies.

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.
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.
Double-blind testingRandom Assignment
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.
Clinical Trial Data Services (CTDS) are an organization that focus on clinical research. The organization also provide understanding about clinical trial processes, for example.

What should be included in a clinical trial
Clinical Trial Service Unit was created in 1975.
The clinical trial management system is used in biochemical, pharmecutical industries and clinical research institutions. The system itself is used to correlate large amounts of data concerning the clinical trial.
