Gender-related sleep duration perception in a Brazilian sleep clinic cohort.
Article in Sleep & breathing = Schlaf & Atmung, 2022. 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
purposeThis study aims to evaluate if gender influences the sleep duration perception in adults referred for polysomnography (PSG).
methodsA cross-sectional study was undertaken from December 2019 to January 2021. Total sleep time was objectively assessed from the overnight PSG and subjectively estimated. The sleep perception index (SPI) was defined by the ratio of subjective and objective values. Diagnosis of obstructive sleep apnea (OSA) was based on an apnea-hypopnea index ≥ 5.0/h. Insomnia was defined by the presence of one or more specific complaints: difficulty falling asleep, difficulty maintaining sleep, and/or waking up earlier than desired. The association between continuous variables and SPI was assessed by linear regression analysis.
resultsThis study enrolled 2,004 outpatients (56% men) who were grouped into four subsamples: controls (n = 139), insomnia (n = 154), OSA (n = 912), and insomnia comorbid with OSA [COMISA] (n = 799). In women, the median SPI differed among groups and ranged from 89 to 102% (p = 0.001); while in men, it ranged from 90% to 99% (p = 0.007). However, no gender-related SPI value differences emerged within each of the subgroups: controls (p = 0.907), insomnia (p = 0.830), OSA (p = 0.070), and COMISA (p = 0.547). The presence of insomnia (β, - 0.101, p < 0.001) or OSA (β, - 0.082, p = 0.001), but not gender (β, - 0.017, p = 0.612), were independent predictors of the SPI.
conclusionIn a clinical referral cohort, no evidence of sex dimorphism emerged for SPI irrespective of the underlying sleep diagnosis.
