Measuring Health Literacy Levels of a Patient Portal Using the CDC's Clear Communication Index.
Article in Health promotion practice, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
Once promised to revolutionize health care, patient portals have yet to fully achieve their potential of improving communication between patients and clinicians. In fact, their use can be detrimental to many consumers due to their limited literacy and numeracy skills. This study demonstrates how applying the Centers for Disease Control and Prevention's Clear Communication Index to a patient portal can be used to identify opportunities for better patient communication and engagement. The Clear Communication Index contains 20 scored items grounded in communication science to enhance patients' understanding of health information. The Index was applied to one portal used by over 80,000 patients in 12 primary care practices: MyPreventiveCare. This portal was selected because of its ability to personalize preventive and chronic care information by internally using content featuring health literacy principles and linking patients' externally to trusted materials. Thirty-seven frequently visited portal pages (17 internal and 20 external) were evaluated based on the Index's four main variables. The overall score for the portal was 72%, which falls below the 90% threshold to be considered clear communication. Internal content scored higher than external (75% vs. 69%). Specific changes to improve the score include simpler language, more specific examples, and clearer numerical explanations.
