The development and psychometric evaluation of the Survey of Obstructive Sleep Apnea Functional Health Literacy.
Article in Sleep medicine research, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 2 of them syntheses 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
OBJECTIVE AND
objectiveObstructive Sleep Apnea (OSA) is a highly prevalent disorder that disparately affects racial/ethnic minorities. OSA functional health literacy can contribute to health disparities. Documenting poor OSA functional health literacy is needed to inform research agendas, policy, and advocacy efforts. The objective of this study is to develop a scale for measuring OSA functional health literacy among diverse audiences and a variety of reading levels and to ascertain its reliability and validity.
methodsDevelopment of the 18-item Survey of OSA Functional Health Literacy (SOFHL) was guided by literature review and input from experts. A convenience sample of persons enrolled in a clinical trial completed the survey (n=194). The psychometric evaluation was conducted using factor analysis to identify the number of dimensions in the SOFHL and their relationship to other domains that are relevant to OSA functional health literacy.
resultsInternal consistency reliability (alpha) was estimated for the resulting scale and correlations with educational attainment and income completed. All respondents were Black and 29% reported average household income less than $10,000 USD. Confirmatory factor analysis provided support for two dimensions: OSA general knowledge (alpha=0.81) and self-efficacy for OSA self-management (alpha=0.71).
conclusionsHigher educational attainment and socioeconomic status were associated with better OSA functional health literacy. These results provide preliminary support for the SOFHL, a measure that can be used to assess OSA functional health literacy.
