Verified Statistics

Every statistic in MedTWIN is computed from your actual data and linked to its source.

How It Works

When you write a statistic in your paper:

1. Computation: MedTWIN runs the calculation on your data
2. Storage: Result stored with full provenance
3. Linking: Statistic in paper linked to computation
4. Verification: Status shown visually
