Abstract

While the Suchey-Brooks method for age estimation is generally accepted in forensic anthropology, its accuracy varies among different populations. This retrospective cross-sectional study aims to test the reliability of the Suchey-Brooks method using Computed Tomography (CT) scans of pubic symphyses of 155 Lebanese living individuals (76 males and 79 females) aged 17 to 98 years. This study reveals that 94.9 % of the sampled individuals fell within the range of 2 standard deviations from the reference mean for predicted age. Additionally, the study assesses phase assignation, overall bias of 1.29, and overall inaccuracy of 8.09, along with strong intra and inter-observer reliability with weighted Cohen’s Kappa (k) 0.901 and 0.82, respectively. Transition analysis was also used to generate new Lebanese age references. The new reference proposed in this study improves the accuracy of age estimation compared to the Suchey-Brooks method when applied to the Lebanese population.

利用CT图像估计黎巴嫩人耻骨联合的年龄

虽然Suchey-Brooks年龄估计方法在法医人类学中被普遍接受，但其准确性在不同人群中有所不同。本回顾性横断面研究旨在通过计算机断层扫描（CT）对155名年龄在17至98岁的黎巴嫩人（76名男性和79名女性）的耻骨联合进行测试Suchey-Brooks方法的可靠性。该研究表明，94.9%的样本个体在预测年龄的参考平均值的2个标准差范围内。此外，该研究评估了相位分配，总体偏倚为1.29，总体不准确性为8.09，以及强大的观察者内部和观察者之间的信度，加权科恩Kappa (k)分别为0.901和0.82。过渡分析也用于生成新的黎巴嫩年龄参考。在本研究中提出的新参考，提高了年龄估计的准确性相比，Suchey-Brooks方法时，适用于黎巴嫩人口。
