The Clinical, Humanistic, and Economic Burden of Idiopathic Hypersomnia in the United States: Analysis of the National Health and Wellness Survey.
Article in Nature and science of sleep, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: Limited self-reported data on the real-world burden of idiopathic hypersomnia exist from a representative sample of the US general adult population. This study described the clinical, humanistic, and economic burden of adults with idiopathic hypersomnia compared to matched adults without idiopathic hypersomnia. Patients and Methods: This cross-sectional study used 2021 and 2023 US National Health and Wellness Survey data. Propensity score matching (1:2) was performed for adults (≥18 years) who self-reported a physician diagnosis of idiopathic hypersomnia and adults without idiopathic hypersomnia (non-idiopathic hypersomnia cohort). Post matching, outcomes were compared between cohorts using cluster-robust regression models; Results: Included were 163 adults with idiopathic hypersomnia (64.4% female, mean age 38.45 years) and 326 matched adults without idiopathic hypersomnia (66.0% female, mean age 39.60 years). The idiopathic hypersomnia cohort had higher prevalence of comorbidities (eg cardiovascular, cardiometabolic, sleep, psychiatric), higher mean Charlson comorbidity index scores (1.43 vs 0.34), and reported worse depression (PHQ-9) and anxiety (GAD-7) and poorer mental health, physical function (SF-36v2, RAND-36), and HRQoL (EQ-5D-5L, SF-6D, EQ-VAS) compared to the matched non-idiopathic hypersomnia cohort ( Conclusion: This study highlights the substantial real-world burden, including comorbidity, HRQoL, and economic, of idiopathic hypersomnia compared to the matched non-idiopathic hypersomnia cohort.
