Defining the strategies to advance health-literacy-friendly patient decision aids based on the ICA-NRM approach.
Article in BMC health services research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPatient decision aids (PtDAs) are evidence-based tools that guide patients in making thoughtful healthcare choices. However, there is a notable shortage of PtDAs that are tailored to the needs of adults with low health literacy (HL). The purpose of this study was to recognize and analyze the standards of HL-friendly PtDAs, thus helping effective shared decision-making (SDM) implementation.
methodsThis study considered five dimensions and 20 sub-dimensions for the HL-friendly PtDA standard via a literature review and expert consultations. Healthcare professionals familiar with SDM from two hospitals in Taiwan completed a questionnaire survey. We used the importance-coincidence analysis (ICA) to evaluate the status of dimensions and sub-dimensions. The decision-making trial and evaluation laboratory (DEMATEL) method evaluated the causal relationships among the proposed dimensions and sub-dimensions and created the network relationship map (NRM). We integrated the ICA-NRM method to develop HL-friendly PtDA improvement strategies.
resultsA total of 84 valid questionnaires were collected, with 43 participants (54.8%) having experience developing a PtDA. The survey results indicated that the content presentation (CP) is the dominant dimension, and the information analysis (IA) is the central dimension affected. The CP dimension aspect impacts the SC (source citation), EA (effectiveness assessment), CS (content settings), and IA dimensions, while the SC dimension influences the EA, CS, and IA dimensions. Then, the EA dimension affects the CS and IA dimensions. The CS dimension only impacts the IA dimension. The dominant sub-dimensions for each dimension are the balanced presentation of options (CS3), options with equal detail (IA2), timely version (SC4), layout structure (CP2), and decision information quality (EA1).
conclusionThis study demonstrated that content presentation is a critical driving factor for HL-friendly PtDA and gives healthcare professionals insights to better implement SDM on HL-friendly PtDA in clinical settings. Using the ICA-NRM method helps clarify the success items of HL-friendly PtDA promotion and provides improvement strategies. CLINICAL TRIAL NUMBER: Not applicable.
