        "abstract": "A systematic review is a specific and reproducible method to search, identify, select, appraise, and summarize all studies relevant to a particular health care question. In this paper, we will review the concept of level of evidence, define the terms systematic review and meta-analysis, and outline the steps in performing a systematic review and meta-analysis with an illustrative example. We will also introduce some important concepts in systematic reviews and meta-analyses like heterogeneity, publication bias, forest plots, and quality assessment. Finally, this review will focus on systematic reviews addressing therapeutic research questions."
