Evidence-based medicine is the practice of deciding treatment from the best available research rather than from custom or authority alone. It is less tidy than the phrase suggests: evidence is often incomplete, sometimes contradictory, and always has to be weighed against the individual patient in front of a clinician.
This topic follows how evidence accumulates — how single studies become systematic reviews, how guidelines are written and revised, and what happens when good evidence and established practice disagree.
A practical guide to reading medical research: study design, sample size, p-values, confidence intervals, absolute vs relative risk, bias, and conflicts of interest.
How randomized controlled trials work: randomization, blinding, control groups, intention-to-treat analysis, and why RCTs are the standard for testing treatments.
Clinical research explained: what it is, the main study types, how trials are regulated and reviewed, and how evidence reaches clinical practice.
