The concept of meta-epidemiology has been introduced with considering the methodological limitations of systematic review for intervention trials. The paradigm of meta-epidemiology has shifted from a statistical method into a new methodology to close gaps between evidence and practice. Main interest of meta-epidemiology is to control potential biases in previous quantitative systematic reviews and draw appropriate evidences for establishing evidence-base guidelines. Nowadays, the network meta-epidemiology was suggested in order to overcome some limitations of meta-epidemiology. To activate meta-epidemiologic studies, implementation of tools for risk of bias and reporting guidelines such as the Consolidated Standards for Reporting Trials (CONSORT) should be done.
元流行病学的概念是在考虑系统评价干预试验的方法学局限性的基础上提出的。元流行病学的范例已经从一种统计方法转变为一种新的方法,以缩小证据与实践之间的差距。元流行病学的主要目的是控制以前定量系统评价中的潜在偏差,并为制定基于证据的指南提供适当的证据。如今,已经提出了网络元流行病学,以克服元流行病学的一些局限性。为了开展元流行病学研究,应该实施工具来评估偏倚风险和报告指南,如 CONSORT(CONsolidated Standards of Reporting Trials)。
