Main Article Content

Sina Moghaddam


Systematic reviews and meta-analyses are vital methodologies in medical research that consolidate and assess evidence pertaining to specific research questions. Systematic reviews adopt a meticulous approach to pinpoint, evaluate, and integrate all pertinent studies on a given topic. Conversely, meta-analyses employ statistical methods to amalgamate results from several studies, yielding a combined estimate of intervention effects or identifying patterns across research.

Both methodologies hold paramount significance in medicine, aiding researchers, clinicians, and policymakers in comprehending the comprehensive evidence on a subject. They underpin evidence-based decision-making, reconcile conflicting results, augment statistical power, spotlight research voids, steer policy and clinical guidelines, optimize resource use, and bolster patient comprehension.

This paper delves into the paramountcy of systematic reviews and meta-analysis in the realm of medicine. It underscores their myriad advantages and their pivotal role in enriching medical knowledge. Contemporary, real-world examples are furnished to elucidate these points. In essence, this paper offers an insightful exposition on the cruciality of systematic reviews and meta-analysis in medicine, underscoring their role in anchoring medical practice in top-tier evidence and ensuring the zenith of patient care.
