Useful. Clear. Accountable.
How we source, publish, review, and correct Clinical Trial Zone content.
Our editorial standard
Every article should answer a real question, explain its scope, and give the reader a useful next step. We favor concrete examples, visible assumptions, and direct language over promotional claims.
Sources and accuracy
We prioritize primary sources such as the FDA, NIH, ClinicalTrials.gov, OHRP, and relevant final guidance. We distinguish regulatory requirements from recommendations and common operational practices. A checklist is not a compliance determination.
References appear with each article. Publication dates reflect verified original dates when available. An updated date records an editorial revision, not a claim that every external source was newly published. Where an original publication date could not be verified during migration, we do not invent one.
Medical and patient education
Patient articles explain research concepts and support conversations with qualified healthcare and research teams. They do not recommend an investigational intervention, promise benefit, or decide eligibility. Medical review is identified only when a qualified, named reviewer has actually completed and documented it. The launch content has not been presented as independently clinically reviewed.
Before publishing new treatment-specific guidance or materially changing statements about safety, eligibility, or care, the publisher must obtain appropriate qualified review. Source review alone is not clinical review.
Tools and examples
Tools disclose inputs, calculations, assumptions, and limitations. Outputs are educational estimates or planning prompts. Initial figures are illustrations, not industry benchmarks or observations from a real study. We do not collect identifiable health information through the tools.
Editorial responsibility
Clinical Trial Zone maintains these resources as a publication. Technology-assisted drafting may support production; the publisher remains responsible for checking sources, examples, links, and final wording before release. We do not invent endorsements, testimonials, credentials, rankings, or performance statistics.
Corrections and updates
Report an issue through our contact page, including the article URL, the statement in question, and a supporting source when possible. Material corrections should be documented in the article's update note. Review high-impact patient and regulatory content at least every six months and other evergreen guidance annually, or sooner when a source changes.
