## 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.
