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

objectiveTo test an educational intervention targeted to health literacy level with the goal of improving glaucoma medication adherence.

methodsOne hundred and twenty-seven veterans with glaucoma were randomized to glaucoma education or standard care. The intervention included a video scripted at a 4th, 7th, or 10th grade level, depending on the subject's literacy level. After six months, the number of days without glaucoma medicine (DWM) according to pharmacy records for the intervention and control groups was compared.

resultsThe number of DWM in the six months following enrollment was similar for control and intervention groups (intervention, n=67, DWM=63 ± 198; standard care, n=60, DWM=65 ± 198; p=0.708). For each subgroup of literacy (adequate, marginal, inadequate), subjects in the intervention group experienced less mean DWM than subjects in the control group and the effect size (ES) increased as literacy decreased: adequate literacy, ES 0.069; marginal, ES 0.183, inadequate, ES 0.363. Decreasing health literacy skills were associated with decreasing self-reported satisfaction with care (slope=0.017, SE=0.005, p=0.002).

conclusionsPatients with decreased health literacy skills may benefit from educational efforts tailored to address their health literacy level and learning style. PRACTICE IMPLICATIONS: Providers should consider health literacy skills when engaging in glaucoma education.
