Overlap Tab

Introduction

The Overlap tab shows how often active concepts co-occur in the same patients.

Overlap matrix

Components

• Group selector: inspect Overall behavior or a specific cluster.
• Overlap visualization: pairwise concept relationships among currently active concepts.
• Pairwise table: sortable/filterable table with metrics such as correlation, Jaccard, and co-occurrence counts.

Pairwise overlap table

Interpretation

• High overlap suggests concepts often appear together in the same patients.
• Compare Overall versus cluster-specific overlap to identify cluster-specific treatment or diagnosis bundles.
• Use overlap findings to guide concept merge decisions in the Mappings tab.
