# PRISMA Key Documents

The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) key documents serve as essential resources for researchers and scholars engaged in conducting systematic reviews—a rigorous method of synthesizing and summarizing existing research. These documents provide structured guidelines and checklists to ensure the systematic review process is transparent, comprehensive, and adheres to high research standards. Here's an overview of the PRISMA key documents:
