About NORC Concierges
The NORC Concierges provide consultation support for the development, design and implementation of nutrition and obesity in clinical and translational research. Our Concierges help investigators with answering the “who, what, when, where, why and how” questions in research. They provide navigation assistance through the UNC research infrastructure and connect investigators to potential mentors, collaborators, and the appropriate support services available on campus. Additionally, the Concierges assist in preparing grant proposals, manuscripts and protocols reviews; identify research gaps and develop research plans; facilitate the development and implementation of pilot grant projects; and provide letters of support and cost estimates for grant proposals.
Concierge services are available to any UNC investigator including a biostatistics or clinical research component in their nutrition or obesity research.
Initial planning and consultation is provided free of charge. Priority is given to members of the NORC. Additional assistance is available for a nominal fee through our recharge service center.
Investigators who receive consultation support or initial planning assistance must cite the NORC grant in all publications resulting from the use of concierge services. The acknowledgement should read “Supported by National Institutes of Health Grant DK056350 to the University of North Carolina at Chapel Hill’s Nutrition Obesity Research Center.” The publication must include a PubMed Central reference number (PMCID) as described in the NIH Public Access Policy. To ensure compliance, please review the UNC Health Sciences Library’s NIH Access Policy Toolkit. Submit a copy of the cited publication to Michelle Collins.
The Biostatistics Concierge provides guidance and support to investigators who need assistance with analyzing and interpreting data for nutrition and obesity-related research.
Importing datasets from excel into SAS, checking datasets for outliers and logic errors, creating new variables and datasets, updating/maintaining existing datasets as new data is generated
Grant Writing & Development
Assistance reviewing grant applications, determining the statistical methods required to address the primary and secondary aims, writing, reviewing and/or editing the statistical analysis and power and sample size sections for proposals
Writing statistical methods sections describing the analyses performed, creating tables, figures and graphs, reviewing the results sections (to ensure statistical analyses are accurately conveyed)
Sample Size & Power Calculations
Determining the appropriate statistical test for study aim(s) of interest, obtaining estimates of potential effect sizes from investigators, using potential sample sizes provided by the investigator to determine power or necessary sample size
Linear regression, t-tests, mann-whitney tests, chi-square tests, logistic regression, mixed models, survival analysis, proportional hazards models, permutation and randomization tests, kaplan-meier curves, ANOVA, ANOCOVA
Discussion of the original problem in order to determine the statistical needs, periodic clarification during the work process to ensure accuracy, preparing and relaying the results in non-statistical language they can understand, reviewing results with the investigator to be sure they know what the results mean
SAS programming for data management, sample size and power calculations and statistical analyses using nQuery or Excel
