Biostatistics is the branch of statistics that is applied to
the field of health and medicine. In clinical research, biostatistics plays a
critical role in the design, conduct, and analysis of clinical trials.
Biostatisticians work closely with researchers, clinicians, and other members of
the study team to develop study designs, sample size calculations, and
statistical analyses that are appropriate for the research question being
studied.
The main activities of biostatisticians in clinical research
include:
- Designing
     clinical trials: Biostatisticians work with the study team to design
     clinical trials that are scientifically and statistically sound, and that
     are appropriately powered to detect the desired treatment effect.
 - Sample
     size calculations: Biostatisticians determine the number of subjects
     needed to ensure that the trial has sufficient statistical power to detect
     the desired treatment effect.
 - Statistical
     analysis: Biostatisticians develop statistical analysis plans and conduct
     statistical analyses to evaluate the safety and effectiveness of the
     investigational product.
 - Data
     management: Biostatisticians may also be involved in the management and
     analysis of the clinical trial data, including data cleaning and validation,
     as well as the development and implementation of data quality control
     measures.
 - Regulatory
     submissions: Biostatisticians may also be involved in the preparation of
     regulatory submissions, including the development of statistical sections
     of regulatory documents such as New Drug Applications (NDAs).
 
Biostatistics plays a vital role in clinical research, as it
helps to ensure the scientific validity and statistical robustness of clinical
trials. Biostatisticians work closely with researchers, clinicians, and other
members of the study team to design, conduct, and analyze clinical trials, and
to develop new treatments and therapies that can improve the lives of patients
around the world.
