Meta-analysis is a statistical tool, which pools data from primary studies focused on the same topic, aiming to obtain a cumulative result in response to a specific research question. Conducting a metaanalysis includes predefined steps, among which the drafting of a protocol, formulating a proper research question, performing a systematic search of the literature with a careful selection process of the studies to be included, an adequate analysis of the extracted data and a proper assessment of bias. The answer to the research question is then provided by interpreting the pooled estimates of the outcomes, the degree of heterogeneity, and the results of sensitivity analysis used to explain and explore the heterogeneity. In this article, we share a brief guide on planning and conducting a meta‐analysis based on the current methodology and our personal experience.

Abstract
Meta-analysis is a statistical tool, which pools data from primary studies focused on the same topic, aiming to obtain a cumulative result in response to a specific research question. Conducting a metaanalysis includes predefined steps, among which the drafting of a protocol, formulating a proper research question, performing a systematic search of the literature with a careful selection process of the studies to be included, an adequate analysis of the extracted data and a proper assessment of bias. The answer to the research question is then provided by interpreting the pooled estimates of the outcomes, the degree of heterogeneity, and the results of sensitivity analysis used to explain and explore the heterogeneity. In this article, we share a brief guide on planning and conducting a meta‐analysis based on the current methodology and our personal experience.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
