Systematic reviews and meta-analyses

A systematic review is a comprehensive process of gathering and carefully analyzing all relevant studies on a specific topic to provide an unbiased summary of the evidence. A meta-analysis is often part of this process, combining data from those studies statistically to identify overall trends or effects. Together, they help researchers and healthcare professionals make informed decisions by offering a clear, evidence-based overview, reducing the uncertainties that come from individual studies. This approach ensures conclusions are based on the totality of available high-quality evidence rather than isolated findings.
