What is the Origin of Meta-Analysis?

The formalization of meta-analysis emerged in the fields of statistics and social science but gained critical importance in medicine as a powerful tool for evidence synthesis. The term itself was coined in 1976, marking the establishment of standardized statistical procedures for combining data from disparate studies. This method addresses the limitations of small sample sizes and conflicting results often seen in individual trials.

What is the Mechanism of Meta-Analysis?

The mechanism begins with a comprehensive systematic review to identify all relevant literature, followed by the statistical pooling of the data using methods like inverse variance weighting to account for study size and precision. A key step is the assessment of heterogeneity, which determines the variability between study results. The final output, typically presented in a forest plot, provides a summary effect estimate and its confidence interval, offering a consolidated conclusion on the intervention's efficacy or safety.

Meta-Analysis

Meaning

A meta-analysis is a rigorous statistical methodology that systematically combines and integrates the quantitative results from multiple independent, methodologically sound research studies addressing the same question. This process generates a pooled, more precise estimate of a treatment effect or association than any single study can provide. It stands as the highest level of evidence in the hierarchy of clinical research, guiding evidence-based medicine and informing clinical practice guidelines for hormonal interventions.
