What Is a Clinical Trial? Phases and How They Work
A clear guide to clinical trials: what they are, the four phases, who can take part, how randomization and blinding work, and how participants are protected.
Research in human participants carries obligations that laboratory work does not. Informed consent, independent review by an ethics committee, and standards such as Good Clinical Practice exist because the history of medical research includes studies that should never have been run.
We cover how those safeguards work in practice, where they are contested, and what it means when a trial is stopped early, published selectively, or never registered at all.

How randomized controlled trials work: randomization, blinding, control groups, intention-to-treat analysis, and why RCTs are the standard for testing treatments.
