RealtimeCampaign.com Helps Give Understanding Concerning Clinical Trial Design

When it comes to clinical trials, a person will deal with either observational or experimental situations. Keep reading to learn more about these, what they mean, and how they are used.

Experimental 

With experimental studies, researchers will assign various patients to a control group or an experimental group. For drug studies (as an example), patients who are in the experimental groups will receive the drug, and patients in the control groups will receive a sugar pill or placebo.

During processes like The Bold Path to PanCAN’s Precision Promise Clinical Trial, patients will not know if they will receive the placebo or the experimental treatment, according to realtimecampaign.com.

Randomly assigning patients to each of the groups will help to ensure that equivalent treatment. Also, control groups and the prospective design will help to ensure a high level of quality control related to the timing and data produced by the intervention, making the findings an invaluable resource for the study.

Observational

With an observational study, the researcher will observe, but will not intervene, which means there is no randomization. With observational studies, it is possible to find correlations between the outcome achieved and the test variable. Caution should be used, though, when assessing that the test variable resulted in a specific outcome. Usually, causality is not inferred. An observational study will be either descriptive or analytical.

Analytical Studies 

These are studies that look at the relationships between the variable and the outcome. The strength of any analytical study is usually dependent on how alike the experimental and control groups are before being exposed to the test variable. The systematic differences between these groups, such as if one group was made up of all women, may make it more difficult to determine if the results were caused by the variable of the test or by the group’s differences. In some cases, larger sample sizes are beneficial because it is likely there will be a higher level of variation among each group.

Descriptive

On the other hand, a descriptive group will gather certain information, such as treatment history, disease history, etiology, and demographics. With descriptive studies, it is not possible to determine the causality between the variable and the outcome. Put simply, it will not determine if x is the result of y. Instead, this type of study will only gather the information required.

Understanding the Difference

When it comes to studies, whether they be developed by a company like Precision for Medicine or another company, there are more than a few things to know and figure out. Being informed and knowing what all the options offer is the best way to help ensure the desired results are achieved. Knowing the differences is one of the best ways to ensure that the right method is used for a study or trial. While this may seem complicated, the in-depth analysis will pay off and help provide the information that is needed for the process in question.
