Most patients were screened for two nights, resulting in 1,043 sleep recordings that each contained data from one night. SA was diagnosed using the Nox T3 portable sleep monitor. An experienced sleep specialist scored the recordings manually using Noxturnal software. A total of 157 women (27%) and 422 men (73%) were examined; 477 (82.7%) had an apnea\u2013hypopnea index (AHI) \u2265 5\/hr, whereas moderate to severe SA (AHI\u00a0\u2265\u00a015\/hr) was diagnosed in 243 patients (42.1%). The AHI derived from automatic and manual scoring showed a good agreement (Pearson's <jats:italic>r<\/jats:italic> coefficient of 0.96). The median difference in AHI was very small (i.e., 0.72 [mean difference, 1.06]), but was statistically significant (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a0.0001). Automatic scoring classified sleep recordings with more than 90% accuracy into SA categories of mild (AHI\u00a0\u2265\u00a05\/hr), moderate (AHI\u00a0\u2265\u00a015\/hr) and severe (AHI\u00a0\u2265\u00a030\/hr). We found a minor (11%\u201321%) mis\u2010estimation of the number of recordings right above and below the boundary separating mild and moderate SA. The accuracy of automatic scoring differed from recording to recording, especially regarding the sensitivity of detecting disrupted breathing events. We found low to moderate agreement for the duration of disrupted breathing events (<jats:italic>r<\/jats:italic>\u00a0=\u00a0.53), for which the automatic scoring led to a statistically significant overestimation by 5.22\u00a0s (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a0.0001).<\/jats:p>","DOI":"10.1111\/jsr.13036","type":"journal-article","created":{"date-parts":[[2020,5,20]],"date-time":"2020-05-20T10:28:43Z","timestamp":1589970523000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Comparing manual and automatic scoring of sleep monitoring data from portable polygraphy"],"prefix":"10.1111","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1434-9524","authenticated-orcid":false,"given":"Stein","family":"Kristiansen","sequence":"first","affiliation":[{"name":"Department of Informatics University of Oslo Oslo Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gunn Marit","family":"Traaen","sequence":"additional","affiliation":[{"name":"Department of Cardiology Oslo University Hospital Rikshospitalet Oslo Norway"},{"name":"Institute of Clinical Medicine Faculty of Medicine University of Oslo Oslo Norway"},{"name":"KG Jebsen Center for Cardiac Research University of Oslo Oslo Norway"},{"name":"Center for Heart Failure Research Oslo University Hospital Oslo Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Britt","family":"\u00d8verland","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Head &amp;
