Harmonized Questionnaires

The HeLTI Research Committee in collaboration with the Harmonization Working Group and Maelstrom Research has developed a core harmonized dataset for collection across the four countries. These common measures are collected at various timepoints throughout the trials (preconception, pregnancy, infancy, and early childhood).

The below list summarizes the harmonized domains, excluding additional site-specific information collected. For a more detailed list of the prospective core variables for all collection timepoints, please visit the Maelstrom Research website here: https://www.maelstrom-research.org/study/helti-hp.
