1 · What the graph read from 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.

2 · The registry

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

objectivesDetermine the relationship between cognitive function and health literacy in heart failure (HF) knowledge in patients with HF.

backgroundHF requires extensive, complex treatment; thus, cognition and health literacy may contribute to understanding and self-management of HF.

methodsParticipants were 330 HF outpatients. Health literacy was assessed using the Medical Term Recognition Test and the Rapid Estimate of Adult Literacy in Medicine. Global cognitive function was screened with the Modified Mini-Mental Status Examination. HF knowledge was assessed with the Dutch Heart Failure Knowledge Scale (DHFKS).

resultsHealth literacy (β = .26, p < .001) and cognition (β = .36, p < .001) were related to DHFKS. Both scores were independently associated with DHFKS (health literacy: β = .13, p = .044 and cognition: β = .30, p < .001).

conclusionsImpairments in health literacy and cognition were independently associated with reduced HF knowledge. Interventions should address both factors to be maximally effective.
