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/

aimsCharles Bonnet syndrome (CBS) is a common complication of visual impairment. However, demographic and clinical characteristics may modify the prevalence and impact of the condition. The aim was to investigate the prevalence of CBS among visually impaired military veterans and the associated impact of visual hallucinations.

methodsCross-sectional screening and survey study of members at Blind Veterans UK, a national charity supporting ex-armed forces men and women with a registered visual impairment. Data were analysed using membership records followed by a prospective CBS screening measure and survey.

results461 military veterans with CBS were identified from 4109 individual records, representing 11.2% (95% CI 10.2% to 12.2%) of the population. From this, 115 members (24.9%) participated in the survey. The average age was 82.5 (±12.3) years and 89.6% were male. The most common ophthalmic condition was age-related macular degeneration (58.3%) and participants had severely reduced visual acuity (average better eye 1.2 (±1.4) LogMAR). Reporting 'bothersome' hallucinations was associated with living with CBS for over 3 years (p=0.01) and hallucinating at least once per week (p=0.05). Diverting attention elsewhere was considered an effective relief strategy among 64.9% (95% CI 56.2% to 73.6%) of those who had used this. Fewer than half (44.3%) had disclosed their symptoms to a hospital doctor and corresponding clinical management was variable.

conclusionCBS was common among visually impaired military veterans and was associated with negative outcomes. However, limitations include identifying cases through retrospective screening and not controlling for visual acuity and rehabilitation. Findings may not generalise beyond veterans in the charity's database. Yet, the findings yield evidence for a therapeutic benefit of relief strategies in managing symptoms and the need to promote dialogue about visual hallucinations between patients and clinicians.
