Anonymization vs redaction of clinical trial data
Redaction removes information. Anonymization transforms it so the document keeps its value. Regulators prefer approaches that keep clinical reports useful.
Redaction blacks out or deletes text. It is simple, but heavily redacted narratives and tables tell researchers very little. It remains the right tool for commercially confidential information (CCI).
Anonymization transforms personal data — replacing identifiers with synthetic values, generalising dates to study days or years, grouping rare categories — so the risk of identifying a participant is low while the clinical story stays intact.
Re-Doc supports both: synthetic data replacement for participant data, and permanent redaction where your team marks CCI or other content to remove.
