Struggling to write a data sources section that withstands audit without sounding promotional? In this lesson, you’ll learn to craft a precise, regulator-ready “template: data sources section for RWE,” with defensible linkage parameters, transparent coverage and representativeness, and clear bias language. You’ll get concise guidance, domain-approved phrasing, real-world examples, and targeted exercises (MCQs, fill‑in‑the‑blank, error fixes) to operationalize neutral, versioned statements that map to EQUATOR-aligned expectations. Finish with a scannable, journal-ready section that earns trust and shortens review cycles.
