Nasal dilator strip therapy for chronic sleep-maintenance insomnia and symptoms of sleep-disordered breathing: A randomized controlled trial
Abstract
To test the impact of nasal dilator strips (NDSs) on insomnia severity, sleep-disordered breathing (SDB) symptoms, sleep quality, and quality of life. Randomized, controlled trial of 4 weeks' duration. Community sample of nonobese, adults with a primary sleep complaint of chronic sleep-maintenance insomnia and mild to moderate SDB symptoms (treatment, n=42; control, n=38). Primary outcomes were four validated scales: Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), Functional Outcomes of Sleep Questionnaire (FOSQ), and Quality of Life Enjoyment and Satisfaction Questionnaire (QLESQ). Secondary outcomes were sleep indices, nonrestorative sleep ratings, and SDB symptoms, assessed retrospectively and prospectively. Both groups received nonspecific education about sleep disorders. Treatment group also received a brief SDB education and nasal strip instructions. At 4 weeks' follow-up, the treatment group demonstrated significant (p=.0001), large improvements in ISI and PSQI (mean Cohen's d=1.18) and significant (p<.02), medium-sized improvements in FOSQ and QLESQ (mean d=0.51) compared to small, nonsignificant changes in control group (Cohen's d range=0.36-0.09). Treatment group change scores among all four primary variables were significantly correlated (mean r=0.50, p=0.01). Secondary prospective and retrospective outcomes showed medium to large improvements in treatment compared to controls for sleep indices (mean d=0.52 vs 0.28), nonrestorative sleep ratings (mean d=0.69 vs 0.11), and sleep breathing symptoms (mean d=0.47 vs 0.09). Significance was obtained for prospective sleep indices (p=0.01), retrospective, and prospective nonrestorative sleep ratings (p=0.003, <0.05), and retrospective sleep breathing symptoms (p=0.03). SDB education and NDSs demonstrated therapeutic efficacy in a select sample of insomnia patients with SDB symptoms. Replication of results requires placebo controls and objectively confirmed SDB cases.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
