Article in JAMA, 1995. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01932996 (Enhancing Smoking Cessation in the Homeless Population), which is not on this map. Cited by 263 papers, 1 of them a synthesis that pooled it.

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.

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.

Abstract

objectiveTo determine the ability of patients to complete successfully basic reading and numeracy tasks required to function adequately in the health care setting.

designCross-sectional survey.

settingTwo urban, public hospitals. PATIENTS: A total of 2659 predominantly indigent and minority patients, 1892 English-speaking and 767 Spanish-speaking, presenting for acute care.

main outcome measureFunctional health literacy as measured by the Test of Functional Health Literacy in Adults (TOFHLA), an instrument that measures ability to read and understand medical instructions and health care information presented in prose passages and passages containing numerical information (eg, prescription bottle labels and appointment slips).

resultsA high proportion of patients were unable to read and understand written basic medical instructions. Of 2659 patients, 1106 (41.6%) were unable to comprehend directions for taking medication on an empty stomach, 691 (26%) were unable to understand information regarding when a next appointment is scheduled, and 1582 (59.5%) could not understand a standard informed consent document. A total of 665 (35.1%) of 1892 English-speaking patients and 473 (61.7%) of 767 Spanish-speaking patients had inadequate or marginal functional health literacy. The prevalence of inadequate or marginal functional health literacy among the elderly (age > or = 60 years) was 81.3% (187/230) for English-speaking patients and 82.6% (57/69) for Spanish-speaking patients, and was significantly higher (P < .001) than in younger patients.

conclusionsMany patients at our institutions cannot perform the basic reading tasks required to function in the health care environment. Inadequate health literacy may be an important barrier to patients' understanding of their diagnoses and treatments, and to receiving high-quality care.
