Objective: To determine the causal relationship between aging and nighttime driving and the odds of injuryamong elderly drivers.Methods: In this cross-sectional study, 5460 car accidents were investigated from 2015 to 2016. The data wereextracted from the Iranian Integrated Road Traffic Injury Registry System. Pedestrian accidents, motorcyclecrashes, and fatalities were excluded from the study. To account for major confounders, Bayesian-LASSO, andtreatment-effect cutting-edge approaches were used.Results: Overall, 801 injuries (14.67%) were evaluated. The results of the univariable analysis indicated thataging and nighttime had adverse effects on the odds of road traffic injuries (RTIs), even after adjusting forthe effect of other variables, these effects remained statistically significant. According to a newly developedapproach, the overall effects of aging and nighttime were significantly and directly correlated with the odds ofbeing injured for older adults (both p<0.001). Our findings indicated that drivers over 75 years old experienced23% higher injury odds (OR=1.23, 95% CI:1.11 to 1.39; p<0.001), while driving at night increased the odds by1.78 times (OR=1.78, 95% CI:1.51 to 1.83; p<0.001).Conclusion: Aging and nighttime driving are significant risk factors for RTIs among elderly drivers. Thishighlights the importance of implementing targeted interventions to enhance road safety for this vulnerablepopulation. Furthermore, the use of advanced Bayesian-LASSO and treatment-effect statistical methodshighlights the importance of utilizing sophisticated methodologies in epidemiological research to effectivelycapture and adjust for potential confounding factors.

Objective: To assess psychometric properties of the European Quality of Life 5-Dimension 3-Level Version(EQ-5D-3L) commonly used tool for measuring road traffic injury (RTI) patients’ quality of life.Methods: The psychometric study assessed the reliability and applicability of EQ-5D-3L through phonesurveys, based on a national cohort platform. Data of 150 RTI patients recruited from the cohort study wereincluded as 50 patients per each follow-up phase (one, six, and twelve months after discharge). A 12- day-timespan was between test and retest. We measured psychometric properties (internal consistency reliability andstability reliability) and agreement using Kappa coefficients and percentages of agreement and Bland-Altmanmethod. Data were analysed using software STATA statistical package.Results: The majority of patients were men (80%) with mean age (SD) of 41(14.7%), employed (78%) andeducated (86%). The Persian version represented high internal consistency reliability at total level (Cronbach’sα=0.81) and moderate to good reliability at phase levels (0.62-0.87). The stability reliability was excellent attotal (ICC=0.98, 95% CI: 0.97, 0.98) and phase levels (0.97-0.98. The kappa agreement coefficients were valuedmoderate to perfect (0.6-0.8, p>0.0001). The Bland-altman plot illustrated high agreement between test andretest scores. No floor and ceiling effects were found.Conclusion: The study revealed that EQ-5D-3L was highly reliable and responsive to be applied through phoneinterviews at three different times post injury and discharge, as no previous study considered its psychometricproperties at various phone follow-ups after RTIs.
