When a review is performed following predefined steps (ie, systematically) and its results are quantitatively analyzed, it is called meta-analysis. Publication of meta-analyses has increased exponentially in pubmed.gov; using the key word "meta-analysis," 1,473 titles were yielded in 2007 and 176,704 on January 2020. ⋯ The aim of this study was to provide CHEST peer reviewers, as well as authors and researchers in training, with tools that can help to improve the quality and timeliness of journal reviews, as well as the quality of the meta-analyses submitted. This article also is intended to be a practical guide to inform authors about the key features of meta-analyses to be considered when producing their review.

A 71-year-old ex-bus driver (ex-smoker, 20 pack-years) was admitted for the first time to the respiratory department because of chronic dry cough and progressive exertional dyspnea with insidious onset 8 years ago. The patient also reported weight loss of about 20 kg in 3 years and proximal muscle weakness. ⋯ In the course of his disease, many diagnostic procedures have been performed including Mantoux tests, five CT scans, a CT-guided biopsy, two bronchoscopies, and an 18F-fluorodeoxyglucose PET scan with inconclusive results. The patient was referred to the hospital to have his long-lasting condition diagnosed and treated.
