All gases were delivered at 37\u00b0C. Severity of headache and other migraine associated symptoms (International Classification for Headache Disorders, 3rd edition criteria) were recorded before and after therapy. The primary endpoint was change in pain scores, while changes in nausea, photosensitivity and sound sensitivity scores served as secondary endpoints. A linear regression model was employed to estimate the impact of individual treatment components and their individual interactions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Fifty-one patients (48\u2009\u00b1\u200915 years of age, 82% women) were enrolled. When compared to the control arm (humidified air), all therapeutic arms showed a significantly greater reduction in pain scores (primary endpoint) at 2\u2009h of therapy with dry oxygen (\u22121.6 [95% CI \u22122.3, \u22120.9]), dry air (\u22121.7 [95% CI \u22122.6, \u22120.7)]), and humidified oxygen (\u22122.3 [95% CI \u22123.5, \u22121.1]). A significantly greater reduction in 2-h photosensitivity scores was also noted in all therapeutic arms (\u22121.8 [95% CI \u22123.2, \u22120.4], dry oxygen; \u22121.7 [95% CI \u22122.9, \u22120.4], dry air; (\u22122.1 [95% CI \u22123.6, \u22120.6], humidified oxygen) as compared to controls. The presence of oxygen and dryness were independently associated with significant reductions in pain and photosensitivity scores.
