A tool that helps design better clinical studies to promote child growth so that every child has a chance to live a healthy and productive life.

FREM Explorer

The FREM Explorer is an easy-to-use point-and-click tool to visualize longitudinal Full Random Effect Models (FREM) built from HBGDki data. The tool enables the user to visualize and perform prospective and longitudinal modeling and prediction of physical growth and cognitive development. In forthcoming versions, the user will be able to evaluate the impact of interventions such as nutrition, water, sanitation, and hygiene. It is also possible to contrast different scenarios.

Intended Use

The FREM Explorer is a visualization tool that facilitates collaboration between data scientists and domain experts in the evaluation and understanding of child growth and development for different scenarios, addressing questions about who, what, and when.

The Challenge

A key challenge for HBGDki, the Foundation, and the global health community is to understand risk profiling and prevention in terms of: who is at greatest risk, what risk factors drive most of the burden, and when in the life cycle does a person have greatest risk. As a response to this challenge, the FREM model was developed to address these questions in terms of risk profiling and interventions, and to improve the efficiency of identifying: who will derive maximum benefit from intervention, what risk factors are most responsive to intervention, and when in the life cycle will targeted interventions be most effective. The FREM Explorer was developed with an easy-to-use and intuitive visualization to facilitate collaboration between data scientists and domain experts, and to improve understanding and use of this complex model.
