Evaluating clinical change and visual function concerns in drivers and nondrivers with glaucoma.
Trial report in Investigative ophthalmology & visual science, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 17 papers, 2 of them syntheses that pooled 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.
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 compare drivers and nondrivers, and to describe the specific concerns of drivers, among individuals with glaucoma.
methodsSix hundred seven patients with newly diagnosed glaucoma treated at 14 clinical centers of the Collaborative Initial Glaucoma Treatment Study were randomly assigned to initial medicine or surgery and were followed up every 6 months. Driving status (drivers versus nondrivers) and patient-reported visual function were determined by the Visual Activities Questionnaire and the National Eye Institute Visual Function Questionnaire. Clinical evaluation included visual field mean deviation (MD) and visual acuity. Statistical comparisons were made using t, chi(2), and exact tests and regression and Rasch analyses.
resultsDrivers were more likely than nondrivers to be male, white, married, employed, and more educated and to have higher incomes and fewer comorbidities. More than 50% of drivers reported at least "some" difficulty performing tasks involving glare, whereas 22% reported at least "some" difficulty with tasks requiring peripheral vision. At 54 months, drivers with moderate/severe bilateral visual field loss (VFL) reported greater difficulty with night driving and tasks involving visual search and visual processing speed than drivers with less bilateral VFL (all P<0.05). Although those who remained drivers over follow-up had better MD in both eyes than those who became nondrivers because of eyesight, a number of drivers had marked VFL.
conclusionsInquiring about specific difficulties with tasks related to glare, visual processing speed, visual search, and peripheral vision in driving, especially among patients with substantial bilateral visual field damage, will enable physicians to more effectively counsel patients regarding driving.
