Scientific Questions Being Studied

I am exploring the data to see what is possible to explore regarding warfarin dose and diet. I hope to be able to find new associations in dietary indices that explain warfarin dose in a prediction model.

Scientific Approaches

This is an exploratory workbench and I will be using mainly visualizations and summary statistics of potential covariates.

Anticipated Findings

This is an exploratory workbench. Potential associations with warfarin dose may be added to dose prediction models in the future.

Demographic Categories of Interest

This study will not center on underrepresented populations.
