Biostatistics and Data Management Services for JHU-Affiliated Researchers

Make a request through the ICTR here. You can make a request as a follow-up to a walk-in clinic visit or if you know your questions require more discussion than the 30-minute clinic can provide. A consultant will be assigned to you and will reach out directly. 

Johns Hopkins researchers (faculty, staff, pre-MD, and post docs) engaged in faculty-led clinical and translational research. 

Every project you bring to use is eligible for five free hours of support from our Center, which is different from many other consulting organizations. Many researchers get free services for multiple projects, sometimes simultaneously. 

Our biostatistical and data management services are comprehensive, and you can come to us at any point in your research lifecycle. For example, we offer help with: 

• Study design, including sample size justification 

• Grant preparation and letter of support 

• Randomization algorithm development and implementation 

• Record sampling and matching using existing database 

• Review of database design for data collection 

• Data visualization techniques 

• Review of the statistical approach / response to reviewers 

• Combining datasets from multiple sources 

• Data management/preparing data for analysis 

• Regression analyses (ANOVA, Linear and Generalized Linear Models) 

• Longitudinal or multi-level data analysis 

• Survival / time-to-event analysis 

• Analysis of survey data 

• Meta-analysis 

• Missing data approaches 

• Multivariate analysis, including PCA and factor analysis 

Yes! Get details here. 

Once the staff assignment has been made to your ICTR request, the consultant will contact the researcher (within a week) to set up an initial meeting.

Come prepared to facilitate the biostatistician’s understanding of your research project. For example, please provide: 

• Description of the research hypotheses 

• Population to be sampled or included in existing source data 

• Outcomes measured and to be analyzed, questions of interest. 

• For sample size/power calculations, clinically significant effect sizes for the primary outcome based on literature or previous pilot studies, and desired levels of precision or power.

Yes. For consistency, you can request a consultant with whom you have previously worked through the walk-in clinic or a previous project.

Co-authorship will be discussed during the collaboration/consultation process. The International Committee of Medical Journal Editors has issued guidelines for when the efforts of the biostatistician(s) should be recognized with co-authorship, which include:  

• Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work 

• Drafting the work or revising it critically for important intellectual content 

• Final approval of the version to be published 

• Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved 

To recognize the NIH-supported grant funding that provides free services through our Center, NIH requests this acknowledgement in any dissemination of supported research: 

Contact the Center to arrange for fee-for-service consulting or to establish a long-term collaboration agreement.
