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 explore whether threshold perimetry can predict fulfilment of the current Swedish and current Norwegian Esterman perimetry standards for Group 1 driver's licence, and differences in compliance between the former and current Swedish visual field standards.

methodsThis study included perimetry examinations from individuals aged ≥18 years who underwent threshold perimetry (24-2 or 30-2) and binocular Esterman visual field testing on the same day during September 2010 to December 2022. Data were collected over 12 years from three Departments of Ophthalmology in Region Örebro County, Sweden. Threshold perimetry data were used to predict fulfilment of the current Swedish and current Norwegian Esterman visual field standards.

resultsIn all, 798 individuals were included. Altogether (33%) failed the Swedish visual field standards for a Group 1 driver's licence in the past; by comparison, a significantly smaller proportion would have failed the current Swedish standards today, (18%) (p < 0.001; McNemar's test). Threshold perimetry, if all test points within the central 20° had values of ≥10 dB, could predict compliance with a sensitivity of 89% and 88% and a specificity of 73% and 78% for the current Swedish and current Norwegian Esterman standards, respectively.

conclusionThreshold perimetry may predict compliance with the current Swedish and current Norwegian Esterman visual field test standard for driving. A larger proportion of individuals may meet the current Swedish visual field standard for a Group 1 driver's licence compared with the former Swedish standard.
