Minnesota: Developing Methods that Provide a More Comprehensive Analysis in Medical Studies

In just a single medical study, multiple approaches and technologies are often used to measure various aspects of the body and its chemical processes that are related to what’s being investigated.

In particular, many studies collect data that are both multi-source and multi-way, meaning data are measured using multiple technologies on multiple kinds of samples or areas, such as body regions, for the same individuals. For instance, a study to identify signs of brain iron deficiency in babies may include different kinds of measurements over many months of molecules and proteins in samples of both blood and cerebral fluid in order to gain a complete picture of what’s happening.

The problem is researchers currently lack a way to analyze the data in a combined way. The result is the combined data has to be split into separate analyses that each capture only one facet of what’s happening in the body and restrict the ability of researchers to accurately see how everything relates together.

To improve this, University of Minnesota School of Public Health researchers have received a $1-million grant from the National Institutes of Health to develop new methods to analyze the data all together at once.

“Combining these data into a ‘joint’ model will lead to identifying accurate composite signs of disease risk and its progression in the body, called biomarkers,” said lead researcher and assistant professor Dr. Eric Lock.

Joining Dr. Lock on the project are professor Dr. Lynn Eberly, as well as other University of Minnesota researchers and students.

Once developed, the methods will be implemented in free, open-source software easily available to other researchers and practitioners.
