DEFINITION:
Systematic Review (SR) is a rigorous, methodical, and transparent synthesis of research evidence on a specific question or topic. Unlike traditional narrative reviews, systematic reviews follow a predefined, replicable protocol to identify, appraise, and summarize all relevant studies, with the goal of minimizing bias and providing the most accurate and reliable answer possible.

KEY CHARACTERISTICS:
- Comprehensive and systematic search strategy
- Explicit inclusion and exclusion criteria
- Data extraction and, where possible, quantitative synthesis (meta-analysis)
- Transparent reporting of methods and results

HISTORICAL CONTEXT:
The systematic review framework emerged prominently in the 1970s and 1980s as researchers sought more objective, evidence-based approaches to summarizing medical literature. Organizations such as the Cochrane Collaboration helped formalize systematic review standards, which are now widely used in health sciences and other fields.

APPLIED EXAMPLE:
A systematic review might address whether progressive resistance training improves strength in older adults, including a systematic search of randomized controlled trials, risk-of-bias assessments, and, if feasible, a meta-analysis to pool effect sizes.

FREQUENTLY ASKED QUESTIONS (FAQs)

How is a systematic review different from a narrative review?
- A narrative review is more descriptive and often subjective, whereas a systematic review follows a structured, replicable methodology to minimize bias.

What is the difference between a systematic review and a meta-analysis (MA)?
- A systematic review is the broader process of collecting and synthesizing evidence; a meta-analysis is a statistical technique that may be included within a systematic review to combine numerical results.
