In Observance of U.S. holiday, Memorial Day, Agilent Cross Lab/ iLab Operations Software will be closed during U.S. hours on Monday May 28th, 2018. EU and APAC support coverage will remain open during this time. We will resume U.S. support hours on Tuesday May 29th, 2018. For urgent matters, please add "Urgent" to the ticket subject and we will prioritize those requests first.

Biostatistics and Epidemiology Core


The Biostatistics Core provides expertise in statistical analysis and study design. We are located in the Battelle Center for Mathematical Medicine (BCCM) suite on the 5th floor of Research Building III.


Services offered:

-Statistical and epidemiologic analysis, including a report of methods and results
-Interpretation of statistical results, including those for manuscript reviews
-Assistance with hypothesis formation and development of specific aims
-Selection of research design and guidance on appropriate statistical methods
-Development of analysis plans
-Power and sample size calculations
-Survey development and validation
-Grant, abstract, poster, and manuscript preparation
-Development of new statistical methods

To request assistance from the Biostatistics Core, please see instructions on the Request Services tab.


Initial Consultation:

Once we have received a request form in our online system, a member of our team will contact you to schedule an initial consultation. During the consultation, the biostatistician assigned to your project will gather information related to the background of the project and the goals of the study, will go through the dataset with you (if available), and will answer any questions you may have. At the end of the consultation the statistician will provide an overview of the analyses or work that will be done and will also provide an estimate of expected costs. The initial consultation is free of charge.



Fee for service:

The Biostatistics Core charges a flat rate of $125/hour for biostatistical support and analysis. These funds can be paid by any type of funding support (e.g. grants, startup funds, departmental funding, etc).


Percent effort on grant:

Based on the number of hours of biostatistics work determined in the initial consultation, core costs can be captured by dedicating a percent effort on a grant application. It is important to note that work covered by this approach will not occur unless the grant is funded.

For researchers with no available funding source, up to 10 hours of statistical support will be offered free of charge.



Regardless of how the costs of biostatistics work are covered, consideration of authorship must be given to any Biostats Core staff member who makes a significant contribution to a publication or otherwise meets the authorship guidelines for a given journal. This includes most analysis work on projects.



-We must receive a request form prior to scheduling the initial consultation.

-We encourage you to contact us as soon as possible concerning data analytic tasks. Although we will make our best effort, because we serve many clients, we cannot promise completion by your grant or abstract deadline unless we are given adequate time.

Request Services


The Biostatistics Core provides assistance to researchers in study design, data analysis, and interpretation of statistical results. For other services such as data entry, database design or data management services, the Core can provide advice on how to set up simple data management systems, and provide a referral to the Research Bioinformatics Core if complex data management services are needed. Please note that the Results sections for papers or abstracts, or the Methods sections for research proposals, must still be written by the investigator. The Biostatistics Core office is located within the office suite of the Center for Innovation in Pediatric Practice in the Research III, 4th floor. The Biostatistics Core is committed to providing outstanding service to investigators at Nationwide Children’s Hospital. The Biostatistics Core is committed to the Research Institute’s vision of supporting cutting edge scientific research at the highest ethical standards.


Biostatistics Monetary Rules of Statistical Services


1) The very first meeting is purely introductory and free, the only expected outcome is approximate number of hours the project will take. 

2) If statistician stays on sufficient percentage of grant preparation he helps to prepare statistical portions of a grant without charges.



Epidemiology is the study of occurrence and distribution of health-related conditions in defined populations.  Its uses are far-reaching and include measuring the incidence or prevalence of, and risk factors for diseases and other health outcomes; evaluating therapeutic interventions; and examining the properties of diagnostic and screening tests (i.e. sensitivity/specificity).  Epidemiologic methods are particularly valuable to those investigators examining a new disease or outcome, new treatment or diagnostic tool, or those who require preliminary information about a particular disease or intervention prior to submitting a grant.  The Epidemiology Core provides assistance to investigators that need or wish to incorporate epidemiologic methods into their research.

The Epidemiology Core services include:

  •     Selection of appropriate study design to answer research questions
  •     Assistance with selecting appropriate study populations, control groups or matching characteristics
  •     Assistance with selecting appropriate measures of exposures and outcomes
  •     Selection of appropriate datasets for secondary analysis
  •     Assistance with basic statistical analysis and interpretation

To Order Services

To order from Core Services you will need a new customer account with iLab. To order a service for the first time, you must register for an account.

To register for an account, go here:

Enter your normal network username and password (you do not need to enter your domain - research, Hospital, etc). You will be prompted to fill out a registration form.

*Pay particular attention to the first question. If you select Research Funds you will be registered as a Research user and only have access to Research Funds. If you select Hospital Funds you will be registered as a Hospital user and have access to both Research and Hospital funds. Click "Request Account" to finish your registration. It will take up to 24 hours to set up your account. You will be notified when you are accepted into your lab and have access to place an order.

Note :  you must be accepted into your requested lab before you will have access to order.
