An Analytic Method to Weight Longitudinal Treatment Patterns for Visualization with Sankey Diagrams

Author: Catherine Wiener

Challenge

Longitudinal treatment pattern data are inherently complex and difficult to visualize in ways that communicate clinical trajectories clearly to clinical and regulatory audiences.

Solution

Target RWE researchers developed and presented an analytic method for weighting longitudinal treatment patterns to generate interpretable Sankey diagrams adjusted for informative censoring and time-varying confounding.

Impact

Providing a validated method for visualizing weighted longitudinal treatment patterns enables Target RWE and pharma partners to communicate complex treatment journey data to clinical, regulatory, and payer audiences.
