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

BACKGROUND/

aimsTo investigate visual impairment and disability, refractive error, and barriers to eye care in the homeless in Cardiff, United Kingdom.

methodsProspective cross-sectional study carried out on participants in homeless shelters in Cardiff. We collected participants socio-demographic profile, ocular history and access to eyecare services. Quantitative data included near and distance visual acuity and a non-cycloplegic refraction.

resultsA total of 100 participants were studied in this study. Prevalence of myopia was 19% and hyperopia 17%. Mean SE (Spherical Equivalent) for myopia -2.42D (95% CI: -1.65 to -3.19 D), for hyperopia this was +2.22D (95% CI: + 1.66 to +2.79). The prevalence of astigmatism was 36% (mean: 1.67 D, 95% CI: -0.88 to 0.94, n = 100). The number of participants with visual acuity (VA) worse than 6/12 was 11% in comparison to 0.89% and 1.1% in the general Cardiff and Welsh population respectively (p < 0.05). Additionally, 1% of the homeless subjects were registerable as blind (visual acuity worse than 3/60 in the better eye). Barriers to eyecare services were high, with 50% not seen by an optometrist within the last 5 years.

conclusionsThese findings indicate a significant disparity in ocular health, visual acuity and refractive error amongst the homeless in comparison with the general population.
