Each model was trained and evaluated using 10-fold cross-validation and to evaluate classification performances of all methods, true positive rate (TPR), false positive rate (FPR), Positive Predictive Value (PPV), F measure and Area Under Receiver Operating Characteristics curve (ROC-AUC) were used.<\/jats:p><jats:p>Results: Results of 10-fold cross validated tests with different variable settings promisingly indicated that the OSA severity of suspected OSA patients can be classified, using non-polysomnographic features, with 0.71 true positive rate as the highest and, 0.15 false positive rate as the lowest, respectively. Moreover, the test results of different variables settings revealed that the accuracy of the classification models was significantly improved when physical examination variables were added to the model.<\/jats:p><jats:p>Conclusions: Study results showed that machine learning methods can be used to estimate the probabilities of no, mild, moderate, and severe obstructive sleep apnea and such approaches may improve accurate initial OSA screening and help referring only the suspected moderate or severe OSA patients to sleep laboratories for the expensive tests.<\/jats:p>","DOI":"10.3414\/me16-01-0084","type":"journal-article","created":{"date-parts":[[2017,6,7]],"date-time":"2017-06-07T12:38:34Z","timestamp":1496839114000},"page":"308-318","source":"Crossref","is-referenced-by-count":24,"title":["Can Statistical Machine Learning Algorithms Help for Classification of Obstructive Sleep Apnea Severity to Optimal Utilization of Polysomno graphy Resources?"],"prefix":"10.3414","volume":"56","author":[{"given":"Asli","family":"Bostanci","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Murat","family":"Turhan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Selen","family":"Bozkurt","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2018,1,24]]},"reference":[{"key":"10.3414\/ME16-01-0084-1","doi-asserted-by":"publisher","DOI":"10.1513\/pats.200709-155MG"},{"key":"10.3414\/ME16-01-0084-2","doi-asserted-by":"publisher","DOI":"10.1164\/rccm.2109080"},{"key":"10.3414\/ME16-01-0084-3","doi-asserted-by":"crossref","first-page":"597","DOI":"10.5664\/jcsm.2172","volume":"8","author":"Berry","year":"2012","journal-title":"J Clin Sleep Med"},{"key":"10.3414\/ME16-01-0084-4","first-page":"313","volume":"17","author":"Tang","year":"2011","journal-title":"Int J Med Biol Front"},{"key":"10.3414\/ME16-01-0084-5","doi-asserted-by":"publisher","DOI":"10.5664\/jcsm.5476"},{"key":"10.3414\/ME16-01-0084-6","doi-asserted-by":"publisher","DOI":"10.1007\/s11325-010-0416-6"},{"key":"10.3414\/ME16-01-0084-7","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2869.2011.00935.x"},{"key":"10.3414\/ME16-01-0084-8","first-page":"1433","volume":"44","author":"Ghandeharioun","year":"2015","journal-title":"Iran J Public Health"},{"key":"10.3414\/ME16-01-0084-9","doi-asserted-by":"publisher","DOI":"10.1378\/chest.116.2.409"},{"key":"10.3414\/ME16-01-0084-10","doi-asserted-by":"publisher","DOI":"10.1590\/S1806-37132011000100012"},{"key":"10.3414\/ME16-01-0084-11","doi-asserted-by":"crossref","unstructured":"Karamanli, H, Yalcinoz T, Yalcinoz MA, Yalcinoz T.
