Trajectories Tab

Introduction

The Trajectories tab compares concept ordering patterns across clusters using median occurrence timing and prevalence.

Trajectories tab

Controls

• Row ordering:
  • Overall order: ranked by overall timing.
  • Top movers: emphasizes concepts whose ordering shifts most across clusters.
  • Most stable: emphasizes concepts with minimal ordering drift.
• Cluster Prevalence (%) (sidebar): when a specific cluster is selected, filters concepts by minimum within-cluster prevalence.

Interpretation

• Concepts that move strongly between clusters can indicate cluster-defining care pathways.
• Concepts with stable ordering are useful anchors for comparing trajectories across cohorts/studies.
• Use this tab together with Dashboard: keep only clinically relevant concepts active, then inspect temporal ordering stability.
