Clinical research is the whole field of investigation carried out in people: trials, observational cohorts, diagnostic accuracy studies, registries and analyses of routine health data. Clinical trials are one part of it, not the whole.
Our coverage follows the path from a laboratory observation to something a clinician can act on, including the many points at which that path stops.
A practical guide to reading medical research: study design, sample size, p-values, confidence intervals, absolute vs relative risk, bias, and conflicts of interest.
Clinical research explained: what it is, the main study types, how trials are regulated and reviewed, and how evidence reaches clinical practice.
