Therefore, it is necessary to evaluate patients{\textquoteright} preoperative general condition and cardiorespiratory capacity to determine the risk of postoperative complications. The objective of this study was to assess whether the stair-climbing test could be used in the preoperative evaluation of lung resection patients to predict postoperative morbidity following thoracic surgery.Methods We performed a systematic review and a meta-analysis on the association between stair-climbing test result and morbidity/mortality after thoracic surgery. We analysed all articles published until May 2020 in the following databases: Pubmed/Medline, Pedro, The Cochrane library, Embase and CINAHL. The risk of bias was assessed using the Quality in Prognosis Studies tool. This meta-analysis is registered as PROSPERO CRD42019121348.Results 13 articles were included in the systematic review for a total of 2038 patients and 6 in the meta-analysis. There were multiple test evaluation criteria: rise time, height, desaturation and heart rate change. For the meta-analysis, we were able to pool data on the height of rise at a variable threshold: risk ratio 2.34 (95\% CI 1.59 to 3.43) with I{\texttwosuperior}=53\% (p=0.06). The threshold for occurrence of complications was estimated at a 10 m climb.Conclusions Our results indicate that the stair-climbing test could be used as a first-line functional screening test to predict postoperative morbidity following thoracic surgery and that patients with a poor test result (\<10 m) should be referred to formal cardiopulmonary exercise testing.}, issn = {0040-6376}, URL = {https://thorax.bmj.com/content/75/9/791}, eprint = {https://thorax.bmj.com/content/75/9/791.full.pdf}, journal = {Thorax} }
