सारांश	PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) is a standardized reporting guideline designed to improve the transparency and completeness of systematic reviews and meta-analyses. Introduced in its current form by Page et al. in 2021 as PRISMA 2020, it provides a 27-item checklist and a four-phase flow diagram that together ensure every stage of a review — from database searching through final inclusion — is documented and reproducible.	Publication bias analysis examines whether the set of studies included in a meta-analysis is a representative sample of all conducted research, or whether studies with non-significant or unfavorable results have been systematically suppressed. Matthias Egger and colleagues introduced the regression-based funnel plot asymmetry test in 1997, providing a formal statistical complement to the graphical funnel plot inspection long used in evidence synthesis.
