title: CBCS3 Baseline and Follow-up Data Dictionaries

description: This dataset contains non-identifiable data dictionaries, codebooks, and analytic scripts developed for the Carolina Breast Cancer Study Phase 3 (CBCS3). The materials support transparency and reproducibility of analyses using CBCS3 data. No participant-level or identifiable data are included. Files include baseline and follow-up data dictionaries, variable descriptions, and sample R/SAS code used for metadata processing and harmonization.

&lt;h2&gt;Data Sharing Process&lt;/h2&gt;

&lt;p&gt;The Carolina Breast Cancer Study (CBCS) welcomes collaboration requests from credentialed researchers, as well as their post-doctoral fellows and graduate students. 
Because CBCS is an ongoing study involving sensitive participant information, 
we have strong ethical and moral responsibilities to protect participant privacy. 
Accordingly, most proposed projects must be reviewed and approved by an Institutional Review Board (IRB). 
Additionally, CBCS cannot share certain data where &lt;b&gt;complete de-identification is not yet possible&lt;/b&gt;.&lt;/p&gt;
&lt;p&gt;As you develop your study question, please use the information provided in this Dataverse to determine whether CBCS contains the data necessary to address your research goals. 
Once ready, complete and submit the &lt;a href="https://ciphr.unc.edu/cbcs-loi-form.php" target="_blank"&gt;&lt;b&gt;Data Sharing Interest Form&lt;/b&gt;&lt;/a&gt;. 
Your submission will be reviewed by &lt;b&gt;Dr. Melissa Troester&lt;/b&gt;, Principal Investigator, 
to ensure scientific merit and to confirm that CBCS has sufficient data to support your proposed work.&lt;/p&gt;

&lt;p&gt;After initial review, you may be invited to submit a Letter of Intent (LOI). 
If approved, final authorization will come from the CBCS Steering Committee.&lt;/p&gt;

&lt;p&gt;Upon Steering Committee approval, and once the study team receives confirmation of 
&lt;b&gt;IRB approval&lt;/b&gt;, a &lt;b&gt;signed Data Use Agreement (DUA)&lt;/b&gt;, and an &lt;b&gt;Authorship Acknowledgment Form&lt;/b&gt;, 
the requested data will then be made available to you in accordance with CBCS data sharing policies.&lt;/p&gt;

&lt;hr&gt;

&lt;h3&gt;Graduate Students and Postdoctoral Fellows&lt;/h3&gt;
&lt;p&gt;If you are a graduate student or postdoctoral fellow working under the direction of 
the CBCS Principal Investigator, a Co-Investigator, or a member of the Steering Committee, 
please submit your proposal through the link below or contact the Project Director for further instructions.&lt;/p&gt;

description: CBCS has been designed primarily to investigate female breast cancer epidemiology, treatment, and outcomes by intrinsic subtype and by population categories. CBCS’s dataset is particularly useful as public health experts, the medical community, and scientists recognize and look into the disparities in breast cancer incidence, treatment, and outcomes across the population, for it certain population groups that make up a smaller proportion of breast cancer patients to achieve statistical significance.
