Effect of age and driving experience on road sign comprehension: a systematic review and meta-analysis of two decades.

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
Road sign comprehension is integral to safe driving, with age and driving experience influencing individuals' ability to interpret signs effectively. This study conducted a systematic review and meta-analysis to synthesise research data from 2004 to 2024 to understand how age and driving experience affect the ability to comprehend road signs. The review identified factors influencing comprehension, including personal characteristics and cognitive design features. Meta-analyses revealed significant differences in accident rates between young and older drivers and novice and experienced drivers. Specifically, the analysis of 3,330 participants (1,746 young drivers and 1,584 older drivers) showed that young drivers were involved in 15.88% points more accidents than older drivers, with high heterogeneity across studies (I² = 99%, P < 0.00001). Similarly, among 1,958 participants (721 novice drivers and 1,237 experienced drivers), novice drivers were involved in 8.68% points more accidents than experienced drivers, also with substantial variability (I² = 98%, P < 0.00001). The review proposed future research directions to improve road sign design, enhance drivers' understanding, and promote road safety, emphasising the importance of advanced cognitive design features and contextual signage solutions. Insights for policymakers, transportation authorities, and researchers were highlighted, stressing the need to assess traffic sign comprehension and to regularly incorporate user-centred design approaches. Sensitivity analyses and publication bias assessment further strengthened the review's findings, laying the groundwork for evidence-based interventions to enhance road safety worldwide.
