Whether you're benchmarking generation systems or validating clinical correctness, RadEval offers **comprehensive and interpretable** metrics out of the box.

            ### 🔬 How it Works:
            
            This tool performs **randomization-based significance testing** to compare multiple systems:
            
            1. **Null Hypothesis**: No difference between systems
            2. **Randomization**: Randomly permute system outputs multiple times
            3. **P-value Calculation**: Proportion of permutations where random difference ≥ observed difference
            4. **Significance**: If p-value < α, reject null hypothesis (systems are significantly different)
            
            ### 📊 Input Format:
            - **References**: Ground truth reports
            - **Systems**: Multiple systems to compare (each with same number of outputs as references)
            - **Metrics**: Evaluation metrics to use for comparison
            
            ### 📈 Output:
            - **Significance Matrix**: P-values for all pairwise system comparisons
            - **Mean Scores**: Average performance of each system on each metric
            - **Bold p-values**: Indicate statistically significant differences
            
            ### ⚡ Performance:
            - **Fast Metrics Only**: This tool only includes BLEU, ROUGE, BERTScore, and Word Count for optimal performance
            - **Excluded Slow Metrics**: RadGraph F1, CheXbert F1 are excluded to ensure reasonable computation time
            - More randomization samples = more accurate p-values but slower computation
            - Recommended: 50-100 samples for quick testing, 1000+ for publication
