Forensic age estimation methods are biased to sex and population; in general, accuracy is reduced when applied to foreign populations. This study assessed the accuracy of the Suchey-Brooks method in contemporary Malaysian individuals and aimed to formulate population-specific standards. Multi-detector computed tomography scans of 355 individuals (165 male; 190 female) of 15-83 years of age were reconstructed using 3D-volumetric rendering in RadiAnt. Pubic symphyseal phase, bias, inaccuracy, and percentage correct age classifications are examined. Transition analysis was used to develop age estimation standards. High observer agreement (κ = 0.763-0.832) and a positive relationship between age and pubic symphyseal phase (r = 0.884-0.90) were demonstrated. Mean inaccuracies were 8.62 and 8.95 years for males and females, respectively; overall correct classification was 97.8%. Transition ages between phases in males were 18.79, 23.29, 28.85, 43.64, and 61.15 years; in females, the corresponding data were 19.77, 22.53, 32.62, 41.85, and 57.39 years.
法医年龄估计方法存在性别和人群偏差；一般来说，应用于外国人群时准确性会降低。本研究评估了苏切伊 - 布鲁克斯方法在当代马来西亚个体中的准确性，并旨在制定针对特定人群的标准。使用RadiAnt中的三维容积重建技术，对355名年龄在15至83岁之间的个体（165名男性；190名女性）进行了多探测器计算机断层扫描。检查了耻骨联合阶段、偏差、不准确程度以及年龄分类正确百分比。采用过渡分析来制定年龄估计标准。结果显示观察者之间具有高度一致性（κ = 0.763 - 0.832），且年龄与耻骨联合阶段之间存在正相关关系（r = 0.884 - 0.90）。男性和女性的平均不准确程度分别为8.62岁和8.95岁；总体正确分类率为97.8%。男性各阶段之间的过渡年龄分别为18.79岁、23.29岁、28.85岁、43.64岁和61.15岁；女性相应的数据分别为19.77岁、22.53岁、32.62岁、41.85岁和57.39岁。
