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

objectiveHealth disparities in patient-reported outcomes by income and education are well documented; however, the impact of health literacy on patient-reported outcomes has received less attention. We examined independent effects of income, education, and health literacy on patient-reported outcomes in systemic lupus erythematosus (SLE).

methodsData from the California Lupus Epidemiology Study (n = 323 participants) were used. Health literacy was assessed with a validated 3-item measure (ability to understand written information, reliance on others to understand written information, confidence in completing written forms). Patient-reported outcomes were administered by interview in English, Spanish, Cantonese, or Mandarin. Generic and disease-specific patient-reported outcomes were examined using the following: 10 Patient-Reported Outcomes Measurement Information System (PROMIS) short forms; the 8 Short Form 36 (SF-36) health survey subscales; and 3 patient-reported SLE disease activity and damage measures. We conducted 2 sets of multivariable analyses: the first examined education, income, or health literacy individually; the second included all 3 simultaneously. All multivariable models included age, sex, race/ethnicity, language, disease duration, and physician-assessed disease activity and damage.

resultsMore than one-third of participants (38%) had limited health literacy (LHL), including >25% with greater than high school education. In multivariable analyses simultaneously considering education, income, and health literacy, LHL was associated with significantly worse scores on all patient-reported outcomes except disease damage. In contrast, disparities by income were seen in only 3 PROMIS scales, 3 SF-36 subscales, and 1 disease activity measure. No disparities by education level were noted.

conclusionWe found significantly worse patient-reported outcome scores among individuals with LHL, even after controlling for disease activity and damage. Whether disparities are due to actual differences in health or measurement issues requires further study.
