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

purposeTo determine the prevalence of and identify factors associated with visual impairment and blindness in institutionalized elderly in Germany.

methodsIn this prospective multicenter cross-sectional study, ophthalmic health care need and provision were investigated in institutionalized elderly in 32 nursing homes in Germany. All participants underwent a standardized examination including medical and ocular history, refraction, visual acuity testing, tonometry, biomicroscopy, and dilated funduscopy. A standardized questionnaire was used to identify factors associated with eye healthcare utilization, visual impairment and/or blindness.

resultsVisual acuity of 566 (94.3%; 413 women and 153 men) of a total of 600 institutionalized elderly was determined. Mean age of the included patients was 82.9 years (± 9.8). Of all participants, 30 (5.3%; 95% CI 3.4-7.2%) were blind and 106 (18.7%; 95% CI 15.5-21.9%) were moderately or severely visually impaired according to the World Health Organization definition. The 136 blind and moderately or severely visually impaired participants were older (OR, Odds Ratio = 1.1, 95% CI 1.0-1.1; p < 0.001), and more likely to have reduced mobility (OR = 12.6, 95% CI 2.8-57.6; p = 0.001).

conclusionA high proportion of blindness and visual impairment was found amongst nursing home residents. Age and reduced mobility were factors associated with an increased likelihood of blindness and visual impairment. Any surveys of blindness and visual impairment excluding nursing homes may considerably underestimate the prevalence of visual impairment and blindness.
