Driver's licence in an adult population with good vision: an exploratory study in two longitudinal very low birthweight cohorts.
Article in BMJ open ophthalmology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo investigate whether being born preterm with very low birth weight (VLBW), lower best-corrected visual acuity (BCVA) or a history of a psychiatric or somatic diagnosis is associated with, or mediates, not having obtained a driver's licence at adult age. METHODS AND ANALYSIS: Potential predictors of no driver's licence were investigated in participants with a mean age of 36 years and BCVA above the legal limit to drive from the Norwegian University of Science and Technology Low Birth Weight Life Study, Norway, and the Helsinki Study of Very Low Birth Weight Adults, Finland, (VLBW n=119, term-born controls n=149).
resultsParticipants with no driver's licence (n=34) had lower BCVA than participants with a driver's licence (mean logarithm of the minimal angle of resolution (SD) -0.03 (0.11) vs -0.101 (0.09), p<0.001. Being born with VLBW and lower BCVA was associated with no driver's licence (OR, 2.5 (95% CI 1.1 to 5.8) and 1.1 per unit (95% CI 1.0 to 1.2), respectively. BCVA was not a mediator of the effect of being born preterm with VLBW.
conclusionIn a population with good visual acuity, being born preterm with VLBW was a predictor for not having a driver's licence, while lower visual acuity further increased this likelihood. A history of a somatic or psychiatric diagnosis was not associated. These findings should be interpreted with caution due to the relatively small sample size and a non-negligible statistical uncertainty. The causal relationship between being born preterm and not holding a driver's licence remains to be investigated.
