Alignment of Patient Health Numeracy with Asthma Care Instructions in the Patient Portal.
Article in Health literacy research and practice, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundAfter Visit Summary (AVS) instructions provided through the patient portal of the electronic medical record can support asthma self-management if patients have the skills to interpret and apply the health information provided. Print literacy demands of patient materials are often higher than the reading ability of patients. However, less is known regarding the numeric demand of patient education materials and how well it aligns with patient health numeracy.
objectivesThis study (1) developed measures of numeric demand for use in the AVS, (2) described the health numeracy demand of AVS instructions for asthma care, and (3) evaluated the association between numeracy demand of materials and patient health numeracy.
methodsWe reviewed personalized AVS instructions for an index visit from 74 adults with moderate or severe asthma recruited from clinics serving low-income urban communities. Using measures of numeric complexity and density developed for this study, numeracy demand of the AVS was compared to the numeracy skills of patients using the validated Asthma Numeracy Questionnaire. KEY
resultsThe numeric complexity and density scales demonstrated content and face validity. The median (range) of the numeric complexity score for AVS instructions was 2.5 (0-46), and density of numeric information was 8% (0%-33%). The median (range) of the Asthma Numeracy Questionnaire was 2 (0-4). There was no association between patient asthma-related health numeracy and the complexity (
conclusionsPatient instructions regarding medications and self-management often include numeric information. Lack of alignment of the numeracy demand of materials with health numeracy skill may be a barrier to communication, particularly among patients of lower health numeracy. PLAIN LANGUAGE SUMMARY: This study developed a way to measure the frequency and complexity of numeric information in instructions given to patients with asthma. No association was found between the difficulty of numeric information provided and the numeracy level of patients. This poses a potential barrier to communication, especially for patients with low health numeracy.
