Screening for orthosomnia: a reliability generalization meta-analysis of the Anxiety and Preoccupation about Sleep Questionnaire (APSQ).
Article in Sleep and biological rhythms, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
This mini-meta-analysis evaluated the internal consistency of the Anxiety and Preoccupation about Sleep Questionnaire (APSQ) across existing studies to assess its potential as an orthosomnia (an obsessive preoccupation with achieving perfect sleep) screening tool. A systematic literature search identified four studies with 2,506 participants using English, Swedish, Turkish, and Arabic versions. Cronbach's alpha ranged from 0.91 to 0.95 across studies. The APSQ demonstrated high overall internal consistency reliability (pooled Cronbach's alpha of the entire ASPQ = 0.93, 95% CI 0.91-0.94), suggesting utility for screening orthosomnia symptoms. The pooled Cronbach's alpha of the first and second factors of the ASPQ were: 0.91 (95% CI 0.89-0.93) and 0.87 (95% CI 0.84-0.89), respectively. APSQ demonstrated high overall internal consistency reliability; however, limited linguistic/cultural representation and significant heterogeneity across studies impact generalizability.
