Patient judgments about hypertension control: the role of patient numeracy and graph literacy.
The purpose of this study was to assess the impact of patient health literacy, numeracy, and graph literacy on perceptions of hypertension control using different forms of data visualization. Forms of visualization included data tables, graphs with raw values, and graphs with smoothed values only. Findings showed that judgments about hypertension data presented as a smoothed graph were significantly more positive than judgments about the same data presented as either a data table or an unsmoothed graph. Hypertension data viewed in tabular form was perceived more positively than graphs of the raw data. Data visualization had the greatest impact on participants with high graph literacy.

This study examined the association between health literacy and medication adherence among Hispanic adults with hypertension. A cross-sectional survey of 1355 Hispanic adults, mostly Dominicans who self-report hypertension was conducted. After controlling for age, sex, birth country, education level, recruitment location, depression, anxiety, and sleep disturbance inadequate health literacy was associated with a lower adherence score.
