## Summary

Researchers have developed a new AI tool called GAVEL (Grounded Adjudication of Variations Across Extracted TimeLines) to compare clinical timelines with their corresponding case reports. This protocol uses an LLM (Large Language Model) to judge discrepancies and provide verdicts, aiming to improve the accuracy of timeline extraction from medical records. The evaluation involved 2,738 findings from two different AI models and two human reviewers. GAVEL was tested on 126 clinical reports, showing that merged timelines preferred by evaluators reduced reported discrepancies significantly. This tool could enhance the reliability of clinical data analysis.

## Key points

- GAVEL compares clinical timelines with case reports
- Improves accuracy of timeline extraction from medical records
- Reduces discrepancies in clinical report comparisons

## Why it matters

This AI tool can improve the quality and consistency of clinical data, which is crucial for patient care and research.
