从天主教应用解剖学研究所的韩国数字数据库中的102个第12胸椎得出了33个线性测量值和2个比率。在35个线性特征中，23个具有性别二态性。我们创建了23个判别函数方程，其性别预测准确率为62.7% - 85.3%。使用两个因素组合的分析得出了更高的准确率：大多数准确率超过80%的方程至少包括一项涉及椎体终板冠状直径的测量。使用判别函数分析的逐步方法，三个变量对性别预测的准确率为90.0%：椎体上终板的冠状直径、椎体前部与中部高度的比率以及左侧乳突和椎弓根的长度。椎体的冠状尺寸体现了主要的性别差异。这些方程将有助于对韩国人该椎骨的性别进行法医鉴别。
Thirty-three linear measurements and two ratios were derived from 102 12th thoracic vertebrae of the Digital Korean database at the Catholic Institute for Applied Anatomy. Of 35 linear traits, 23 were sexually dimorphic. We created 23 discriminant function equations that predicted sex with 62.7-85.3% accuracy. The analysis using combinations of two factors gave higher accuracies: most equations with accuracies over 80% included at least one measurement involving the coronal diameter of the vertebral endplate. Using stepwise method of discriminant function analysis, three variables predicted sex with 90.0% accuracy: the coronal diameter of the superior endplate of the vertebral body, the ratio of anterior to middle height of the body, and the length of the left mammillary process and pedicle. Coronal dimensions of the vertebral body represented the major sex difference. These equations will help forensic discrimination of the sex of this vertebra among Koreans.
