The CTSI-CN Biostatistics and Research Design group has years of experience providing best practices for study design and analysis to enable efficient, high impact translational studies. Our experts serve the research community by providing statistical consultation, analysis, and proposal development support at a reasonable cost, with the first 4 hours of support provided free to every investigator. Explore the services and education they offer below.
Our group creates and regularly adds presentations, videos, and links to a variety of study designs and analysis techniques that can be found within the CTSI-CN Virtual Organizer.
Our team is trained on a variety of statistical techniques from basic hypothesis testing to advanced modeling techniques. We also provide power and sample size calculations and will write the methods sections for proposal submissions or manuscripts. We primarily program in SAS, Stata, and R, and regularly partner with Children’s and GW Informatics staff on Big Data analytic and reporting projects.
Our team provides expert consultations with investigators to assist with proposal development, including:
- Formulating aims and goals
- Hypothesis development
- Power and sample size calculations
- Developing methodology sections
- Critique and Review
- Cohort and Case Control
- Survey instruments
- Single and Multi-site trials
