Health Literacy and Outcomes Among Patients With Heart Failure: A Systematic Review and Meta-Analysis.
Synthesis in JACC. Heart failure, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 61 papers, 2 of them syntheses 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
objectivesThe purpose of this study was to determine if health literacy is associated with mortality, hospitalizations, or emergency department (ED) visits among patients living with heart failure (HF).
backgroundGrowing evidence suggests an association between health literacy and health-related outcomes in patients with HF.
methodsWe searched Embase, MEDLINE, PsycINFO, and EBSCO CINAHL from inception through January 1, 2019, with the help of a medical librarian. Eligible studies evaluated health literacy among patients with HF and assessed mortality, hospitalizations, and ED visits for all causes with no exclusion by time, geography, or language. Two reviewers independently selected studies, extracted data, and assessed the methodological quality of the identified studies.
resultsWe included 15 studies, 11 with an overall high methodological quality. Among the observational studies, an average of 24% of patients had inadequate or marginal health literacy. Inadequate health literacy was associated with higher unadjusted risk for mortality (risk ratio [RR]: 1.67; 95% confidence interval [CI]: 1.18 to 2.36), hospitalizations (RR: 1.19; 95% CI: 1.09 to 1.29), and ED visits (RR: 1.17; 95% CI: 1.03 to 1.32). When the adjusted measurements were combined, inadequate health literacy remained statistically associated with mortality (RR: 1.41; 95% CI: 1.06 to 1.88) and hospitalizations (RR: 1.12; 95% CI: 1.01 to 1.25). Among the 4 interventional studies, 2 effectively improved outcomes among patients with inadequate health literacy.
conclusionsIn this study, the estimated prevalence of inadequate health literacy was high, and inadequate health literacy was associated with increased risk of death and hospitalizations. These findings have important clinical and public health implications and warrant measurement of health literacy and deployment of interventions to improve outcomes.
