From the inception of the CALERIE I studies, data management and many day-to-day analyses were performed by Manjushri Bhapkar. Ms. Bhapkar began a well-deserved retirement in August 2025. Currently, Steven Kemp serves as the point person for CALERIE analyses along with Senior Statistician, Dr. Carl Pieper.
Database Maintenance
There are occasional changes in the main database which need to be updated in the database on the website. Additionally, when specimens are requested, after analysis, the result data values are sent back to the data center and absorbed into the main database. Finally, Ms. Bhapkar maintains the identity link between the specimens and the extant database for the main trial.
Database Assistance
Advice on procedures and methods for linking databases to produce analysis work files is available. Building the databases is generally performed in SAS. However, using the comma delimited CSV CALERIE files, users can transfer the CALERIE database to any analytic programs. Steve Kemp (calerie@duke.edu) can assist.
Analysis Assistance
Along with Dr. Carl Pieper, Steve Kemp can provide analytic assistance – informing on the analysis methods used in prior CALERIE analyses, providing advice on data handling as these decisions interface with statistical procedures, and advising on methods employed to date in CALERIE which incorporate the common and unique design issues inherent in the analysis of a longitudinal clinical trial. Depending on the level of complexity, analytic questions using CALERIE will be addressed by either Mr. Kemp or Dr. Carl Pieper. While assistance and advice are freely offered, programming is not available from CALERIE.
