Study Design and Biostatistics (SDAB)
Biostatistical Analysis Assistance
The primary goal of the statistical data analysis is to perform the analyses pertaining to the research questions of interest to the investigator, which are best presented as the specific aims of the study. Methods employed range from the most basic descriptive statistics to state-of-the-art statistical methods that may involve multi-stage modeling, resampling methods for estimation and statistical tests, and, in some cases, development of new methods. More information on the latter item may be found under the Biostatistics and Epidemiology Program (BEMP).
In many cases, when they have sufficient training to do so and access to appropriate software, investigators perform analyses themselves with guidance from SDAB members. This type of support is especially important to investigators on training grants. Alternatively, a member of the BAC/DBMC, supported by the CTSA, is available to conduct limited analyses, with funding arrangements made for more extensive needs. This component of the SDAB is crucial to the success of the core, both for investigators with limited expertise and/or resources, and for the application of more complicated methodology. Manuscript support is included as part of data analysis and includes composition of methods sections, production and/or review of tables and other statistical results presented, as well as interpretation of results and contribution to discussion sections of manuscripts as appropriate.
