The HHEAR Data Center offers access to de-identified data from all studies accepted into the CHEAR and HHEAR programs. Our study-level search enables users to explore commonalities across studies based on various characteristics such as demographics, environmental exposures, and health data. Users can identify how many studies meet their criteria and then choose to download either single or multi-study datasets. These datasets are harmonized to the HHEAR ontology, ensuring interoperability and the use of common codebooks. Additionally, users have the option to access original study-specific files, retaining original variable names and codebooks.
