Agreement with the Coordinating Center and, if applicable, the CHS Central Laboratory about the costs needed to perform an ancillary study is required for Steering Committee approval.
Definition of an Ancillary Study
An ancillary study is an investigation which is not part of the central, NHLBI-funded CHS protocol but uses CHS participants, samples, or data collected by CHS. An ancillary study can involve acquisition of additional data which are not compiled as part of the standard CHS data set, or analysis of existing CHS data only in a paper or series of papers as part of a new external funding application.
Support for ancillary studies is derived from sources other than CHS grant or contract funds. Examples include studies funded by investigator-initiated NIH research awards (R01s), grants from academic institutions, private sources (e.g. drug companies), or those performed at no cost (generally because of the special interest of a researcher).
Rationale for Ancillary Studies
Investigators are encouraged to propose and conduct ancillary studies. Such studies enhance the value of CHS and ensure the continued interest of the diverse group of investigators who are critical to the success of the study as a whole. They provide an exceptional opportunity for investigators, either within or outside of CHS, to conduct additional projects at minimal cost.
Types of Ancillary Studies
There are two types of ancillary studies in CHS:
