All subjects were tested twice, 2-3 weeks apart; the OSA group after the commencement of CPAP. The Epworth Sleepiness Score (ESS) in patients was measured at the same visit. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; The test score at visit 1 was 26.7% for normal subjects and 31.6% for patients with OSA. At visit 2, the test score was 25.0% for normal subjects and 29.9% for patients with OSA. The groups showed a small and identical improvement over the trial period in the test score, of 1.7% (p = 0.01 and p = 0.03 for the normal and OSA groups, respectively). The group with OSA experienced a drop in ESS of 7.5 (SD 5.5) points following treatment. &lt;b&gt;&lt;i&gt;Conclusion:&lt;\/i&gt;&lt;\/b&gt; The small and identical improvement in both groups suggests only a similar learning effect rather than any improvement due to reduced sleepiness.<\/jats:p>","DOI":"10.1159\/000354797","type":"journal-article","created":{"date-parts":[[2013,12,2]],"date-time":"2013-12-02T12:03:01Z","timestamp":1385985781000},"page":"144-148","source":"Crossref","is-referenced-by-count":1,"title":["Effect of Continuous Positive Airway Pressure Treatment for Obstructive Sleep Apnoea on Visual Processing of Degraded Words"],"prefix":"10.1159","volume":"87","author":[{"given":"Katie","family":"Proudlove","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ari","family":"Manuel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rachel","family":"Hall","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Romelie","family":"Rieu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mauricio","family":"Villarroel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John","family":"Stradling","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2013,11,30]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.2337\/diacare.27.5.1047"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1136\/thx.2005.057745"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1097\/IAE.0b013e318259568b"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1111\/j.1464-5491.2010.02962.x"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1159\/000334090"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1111\/j.1440-1843.2012.02255.x"}],"container-title":["Respiration"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/354797","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/354797","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T18:02:48Z","timestamp":1745431368000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000354797"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,11,30]]},"references-count":6,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2014,2,1]]},"published-print":{"date-parts":[[2014,2,6]]}},"URL":"https:\/\/doi.org\/10.1159\/000354797","archive":["Portico"],"relation":{},"ISSN":["0025-7931","1423-0356"],"issn-type":[{"type":"print","value":"0025-7931"},{"type":"electronic","value":"1423-0356"}],"subject":[],"published":{"date-parts":[[2013,11,30]]}}}
