A clinical researcher is interested in summarizing the evidence on angiotensin receptor blockers (ARBs) for stroke prevention. She performs the following steps:
- Conducts a comprehensive search of PubMed, Embase, and the Cochrane Library using a pre-defined search strategy.
- Applies strict inclusion and exclusion criteria determined a priori.
- Independently screens titles, abstracts, and full texts for eligibility.
- Assesses the methodological quality and risk of bias of each study.
- Extracts data and provides a detailed narrative synthesis of study findings without statistically combining effect sizes.
