Usage Notes

Risk Levels

Use consistent terminology:

Very High: Near-certain or extremely likely outcome
High: Substantially increased risk, intervention strongly recommended
Moderate: Elevated risk, intervention recommended
Low: Baseline or minimal risk

Best Practices

Quantify when possible — Include quantification with percentages or rates when data exists
Provide context — Use description to explain what the risk level means clinically
Be transparent — Indicate when risk estimates are based on limited data
