Guide to Using the Public Database

When downloading publically available CALERIETM data, please acknowledge the current funding supporting this site’s infrastructure and the ongoing CALERIE Network (R33 AG070455). Also, please consider reaching out to original CALERIETM Phase 2 investigators for any questions and clarifications about the original study design and data acquisition that may impact your analyses; email for more information.

Data Repository Contents

This section consists of the technical documents describing, in detail, the public use dataset.  It is most often useful in creating an analysis data set.   The data described within is optimal for building a Person-Time data set – one observation per each visit a subject provided information.  

Documents included in this section, each of which will open in a new window:

Data Handling Rules

Information in this section translates how raw data are converted to the databased items and outlines data cleaning procedures established by the CALERIE Committee. They contain the ‘rules’ for derivations of variables, defining/coding variables, range limits, and allocation to refusal and missing values.  These are of most use for the majority of Network Investigators when the precise definition of variables is required.

CALERIETM Phase 2 Study Forms

This section contains all the Case Control Report Forms, Non-Case Control Report Forms, Visit Forms, Data Dictionary, and Miscellaneous Forms.

The CALERIE2 Annotated Forms map the data headings in the database to individual items in the data collection forms.  These will be useful when a researcher wants to determine exactly how variables were collected and mapped into the database.
