Facilitating Harmonization of Variables in Framingham, MESA, ARIC, and REGARDS Studies Through a Metadata Repository
Key result
New open-access metadata portal harmonizes variables across four major cardiovascular cohort studies.
Why the study?
Cardiovascular prevention research requires integrating and harmonizing diverse datasets to increase generalizability, sample size, and representation of understudied populations.
Population
Data from 4 cohort studies (REGARDS, FHS, MESA, and ARIC)
Design
Development of an open-access repository, interactive online portal, and harmonization framework

Intervention
Development of an open-access repository and interactive online portal for accessing metadata and code to harmonize data
The creation of an open-access repository for harmonizing data from major cardiovascular cohorts (REGARDS, FHS, MESA, ARIC) facilitates collaboration, reproducibility, and research into cardiovascular disease disparities.
Cite This Study
Mallya et al. (2023) studied Cardiovascular disease. Metadata repository and interactive online portal was evaluated. An open-access metadata repository and interactive online portal was successfully developed to harmonize variables across four major cardiovascular cohort studies (REGARDS, FHS, MESA, and ARIC).
