# Dataset Information

Weekly **clinical trial intelligence** covering regulatory progress, sponsor metadata, and modelled outcomes, sourced from **SOV.AI**. Each row describes a single trial snapshot with rich metadata plus predictive scores for success, duration, and economic impact.

- **Coverage**: Global clinical trials mapped to corporate tickers or sponsor labels
- **Update cadence**: Weekly, with an average of **1,052 new trials** added per week
- **Performance**: Predictive models achieving **87% ROC-AUC** on held-out validation data
- **Contents**: Trial identifiers, sponsor information, design details, eligibility, outcomes, site geography, and SOV.AI predictive scores

## Data Source
Data provided by SOV.AI. Access programmatically via:

```python
import sovai as sov
df_clinical = sov.data("clinical/trials", full_history=True)
```

## Notes
- Date fields are normalised to ISO-8601 (`YYYY-MM-DD`).
- Boolean columns use nullable boolean semantics to preserve missing values.
- `success_prediction`, `success_composite`, and `economic_effect` are probabilistic or index scores between 0–1.
- `duration_prediction` and `trial_duration` express durations in days.
