Sleep disruption and premolar absence, NHANES, 2017-2020: A cross-sectional study.
Article in Community dentistry and oral epidemiology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
objectiveOrthodontic treatment often involves four first premolar extractions. There is concern that the retraction of the anterior teeth due to extraction of first premolars may constrict tongue space and will reduce oral cavity and oropharynx space. Constricted airways are often associated with sleep disordered breathing (SDB) and sleep disruption. The aim of this study was to determine if there is an association of SDB factors with the absence of first premolars.
methodsA cross-sectional study was conducted using National Health and Nutrition Examination Survey (NHANES) 2017-March 2020 data on participants, aged 18-65 years (n = 4742). Variables of interest included self-reports of SDB (symptoms of disrupted sleep such as snoring, snorting, daytime sleepiness, and inappropriate number of hours of sleep). Data for the presence/absence of first premolars were gathered from the oral examination section of NHANES. An assumption was made that absence of four first premolars in dentate participants indicated extractions for orthodontic treatment. Data analyses were conducted with Rao Scott chi squared test.
resultsThere were no significant associations of SDB and symptoms of disrupted sleep associated with the absence of four first premolars in dentate participants.
conclusionConcerns of the impact of first premolar extractions on SDB were not supported with this study.
