The frequency of abnormal proteinuria, defined as protein excretion greater than the highest rate observed in group I (46 \u03bcg\/min), was 14% in group II and 64% in group III (p &lt; 0.05). There were no significant differences in age, body weight, body surface area, blood pressure, or indices of sleep apnea between OSAS patients with and without proteinuria. Although the mechanism is unclear, this study shows that nocturnal protein excretion rates are commonly elevated in patients with OSAS.<\/jats:p>","DOI":"10.1159\/000185239","type":"journal-article","created":{"date-parts":[[2008,12,12]],"date-time":"2008-12-12T10:27:44Z","timestamp":1229077664000},"page":"35-38","source":"Crossref","is-referenced-by-count":30,"title":["Nocturnal Urinary Protein Excretion Rates in Patients with Sleep Apnea"],"prefix":"10.1159","author":[{"given":"Allan H.","family":"Sklar","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bashir A.","family":"Chaudhary","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rollie","family":"Harp","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2008,12,9]]},"container-title":["Nephron"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/185239","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000185239","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T17:54:52Z","timestamp":1777658092000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000185239"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2008,12,9]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000185239","archive":["Portico"],"relation":{},"ISSN":["1660-8151","2235-3186"],"issn-type":[{"value":"1660-8151","type":"print"},{"value":"2235-3186","type":"electronic"}],"subject":[],"published":{"date-parts":[[2008,12,9]]}}}
