How to read a systematic review without overconfidence
A practical guide to GRADE thinking, heterogeneity, and pooled estimates.
Educational information only — not medical advice. This page does not diagnose conditions, recommend treatment, or replace care from a qualified clinician. The Peptide Center uses an evidence-first editorial process: regulatory sources, trial registries, and peer-reviewed research take priority; uncertainty is stated rather than filled with promises.
A systematic review uses explicit methods to find and synthesize studies on a question. Quality varies. A review is only as strong as the underlying trials, the comparability of included studies, and the transparency of its methods.
