This overview paper introduces the PhenX (consensus measures for Phenotypes and eXposures) initiative to identify common measures and common data elements for use in TRR which have been disseminated in the PhenX Toolkit (https://www.phenxtoolkit.org/). It describes the work of the scientific panel that provided guidance to the project and the TRR Core Collection of measures recommended for use by investigators conducting human-subject tobacco regulatory or related tobacco control research. The use of PhenX TRR measures will promote collaborative research and facilitate data interoperability and validation of outcome assessments to inform the FDA CTP’s regulatory activities. ER -
