Dashboard Composite Plot

Introduction

The Dashboard is the primary analysis surface in CohortContrast. It combines effect size, prevalence, timing, and demographics for active concepts in one plot and one table.

Dashboard composite plot

What the composite shows

The chart is concept-centric (one row per concept) and combines:

• Event occurrences: distribution of first occurrence timing.
• Prevalence/Enrichment: target prevalence and prevalence difference ratio.
• Age: concept-level age estimate relative to cohort context.
• Male proportion: concept-level sex distribution.
• Cluster columns: per-cluster prevalence summaries for the active clustering.

How to use it

1. Apply sidebar filters and inspect which concepts remain active.
2. Switch cluster view (All, Cluster 1, Cluster 2, …) to compare within-cluster behavior.
3. Use table filters and the Show column for manual inclusion/exclusion.
4. Click Apply Table Selection to persist manual visibility updates.

5. Enable ordinal rows for concept’s where on average >2 occurrences happen.

Interpretation guidance

• High prevalence difference ratio with solid target prevalence often indicates robust cohort contrast.
• Cluster-specific prevalence columns help distinguish global signals from cluster-local signals.
• Age/sex columns can expose clinically meaningful subgroup effects and potential confounding patterns.
