The association of health literacy with adherence and outcomes in moderate-severe asthma.
Trial report in The Journal of allergy and clinical immunology, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 2 registered trials, which are not on this map. Cited by 64 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.

Abstract
backgroundLow health literacy is associated with poor outcomes in asthma and other diseases, but the mechanisms governing this relationship are not well defined.
objectiveWe sought to assess whether literacy is related to subsequent asthma self-management, measured as adherence to inhaled steroids, and asthma outcomes.
methodsIn a prospective longitudinal cohort study, numeric (Asthma Numeracy Questionnaire) and print literacy (Short Test of Functional Health Literacy in Adults) were assessed at baseline in adults with moderate or severe asthma for their impact on subsequent electronically monitored adherence and asthma outcomes (asthma control, asthma-related quality of life, and FEV1) over 26 weeks, using mixed-effects linear regression models.
resultsA total of 284 adults participated: age, 48 ± 14 years, 71% females, 70% African American, 6% Latino, mean FEV1 66% ± 19%, 86 (30%) with hospitalizations, and 148 (52%) with emergency department visits for asthma in the prior year. Mean Asthma Numeracy Questionnaire score was 2.3 ± 1.2 (range, 0-4); mean Short Test of Functional Health Literacy in Adults score was 31 ± 8 (range, 0-36). In unadjusted analyses, numeric and print literacy were associated with better adherence (P = .01 and P = .08, respectively), asthma control (P = .005 and P < .001, respectively), and quality of life (P < .001 and P < .001, respectively). After controlling for age, sex, and race/ethnicity, the associations diminished and only quality of life (numeric P = .03, print P = .006) and asthma control (print P = .005) remained significantly associated with literacy. Race/ethnicity, income, and educational attainment were correlated (P < .001).
conclusionWhile the relationship between literacy and health is complex, interventions that account for and address the literacy needs of patients may improve asthma outcomes.
