  • (1888PressRelease) October 22, 2021 - CD BioSciences, a provider of comprehensive clinical trial services with over a decade of experience, recently introduces sample size calculation service for drug development in clinical trials. Researchers now can develop a simple and comprehensible strategy for sample size calculation at CD BioSciences, with the help of it statistical experts.

    In the process of designing a research study, selecting adequate sample size and power calculation are key steps that need to be considered early. A sample size that is too small will not provide reliable answers to the study questions being asked or research hypotheses needing to be tested. A sample size that is too big can make the study unwieldy, wasting both time and efforts. An adequate sample size uses resources and time in the most cost-effective manner and is essential to produce useful research findings.

    Scientists at CD BioSciences are experienced in various types of study design in many different clinical areas such as central nervous system, cardiovascular, immunology, pediatric, oncology and hematology. “Our statistical experts will help you to develop a simple and comprehensible strategy for sample size calculation. To achieve that, the design of sample size calculation for the various clinical trials constitutes most of our work.” said Helen James, senior scientist at CD BioSciences.

    In the significance level, power and magnitude of the difference (effect size) affect the sample size. In simple terms, in a clinical trial or animal study, the size of the difference detected between two groups affects the sample size. If a researcher wants to detect a larger difference, he or she needs to recruit more patients or samples. To avoid the need of extremely large amount of patients or samples, its experts will calculate out a sufficient number of subjects for getting the minimal important difference for your trial. Besides, if there is more than one outcome in your trial, CD BioSciences experts will choose the largest sample size to make all the outcome measurements fully powered.

    “This new service will help our clients focusing on clinical areas to get better result in the project and we’ll provide them more access to new, and potentially more effective services. In addition, CD BioSciences’ experienced statisticians can also conduct an appropriate power calculation to meet researchers’ requirements for clinical trial. Power means the ability of study findings to detect an effect. It goes hand-in-hand with sample size. We will continue to advance their studies by expanding our clinical related services offering.” added Helen.
