Poor visual functions have been reported to be related to the occurrence of road traffic accidents.
To review the association between visual function and road traffic accidents (RTAs) from published relevant empirical studies.
Worldwide.
A random effects (RE) model meta-analysis was conducted using STATA 18. Statistical tests conducted include meta-summary statistics, RE meta-analysis (forest plot), meta-regression (relationship between mean age and effect sizes), funnel plots, Egger's and Begg's tests for publication bias and small study effects.
A total of 17 relevant studies, which were either cross-sectional or observational by design, were included in the meta-analysis. Reported effect sizes were within computed confidence intervals (CI) at 95%. The computed Q test of homogeneity was 61.94. The overall mean effect size of 1.43 (95% CI of 0.985-1.883) was statistically significant at a 5% level (Z = 6.26; p 0.001). The I-squared = 62.17% (p = 0.00) confirmed moderate heterogeneity and the Q-value of 61.94 (p = 0.00) rejected the null hypothesis that the effect size was the same in all the studies. The funnel plot showed that the remaining majority of 13 studies were within the funnel plot on the right-hand side of the line of no effect.
These results provide evidence of associations between visual functions and RTAs, and highlight the need for targeted interventions and further research to address the challenges associated with impaired visual functions and road safety.Contributions: The study contributes to the understanding of the implications of visual functions for road safety.
据报道，视力不佳与道路交通事故的发生有关。
从已发表的相关实证研究中综述视力与道路交通事故（RTA）之间的关系。
全球范围。
采用 STATA 18 进行随机效应（RE）模型荟萃分析。统计检验包括荟萃汇总统计、RE 荟萃分析（森林图）、荟萃回归（平均年龄与效应大小之间的关系）、漏斗图、Egger 和 Begg 检验发表偏倚和小样本效应。
共有 17 项相关研究被纳入荟萃分析，这些研究设计均为横断面或观察性研究。报告的效应大小在 95%置信区间内。计算的 Q 检验同质性为 61.94。总体平均效应大小为 1.43（95%CI：0.985-1.883），在 5%水平上具有统计学意义（Z=6.26；p<0.001）。I²=62.17%（p=0.00）证实了中度异质性，Q 值为 61.94（p=0.00）拒绝了效应大小在所有研究中相同的零假设。漏斗图显示，其余 13 项研究中的大多数都在效应线右侧的漏斗图内。
这些结果为视力与 RTA 之间的关联提供了证据，并强调需要有针对性的干预措施和进一步的研究，以应对与视力受损和道路安全相关的挑战。
本研究有助于理解视力对道路安全的影响。
