摘要

掌纹是法医学调查中最重要的人体识别工具之一。指纹通常用于法医性别估计,以通过消除过程缩小嫌疑人的范围。这项研究的目的是测试Badiye及其同事之前提出的一种根据手掌三径间距离进行性别估计的新方法[《法医学与法律医学杂志》,2019;65(3月):22-26]是否可以用作法医性别鉴定的主要工具。在这项研究中,使用传统的油墨印刷方法收集了200名孟加拉印度教成年人(100名男性,100名女性)的双侧掌纹,并进行了分析。表格中提供了描述性统计数据,并进行了线性判别分析,以估计三径向距离中的两性异形程度,并找出具有最强性别辨别潜力的变量。二元逻辑回归分析(BLR)用于推导性别估计方程。使用线性判别分析发现,两性异形具有统计学意义(p<0.001),左手掌和右手掌的性别鉴定准确率分别为79.0%和79.5%。已经发现,a和t三半径之间的距离对该模型的影响最大,其次是abcd-t组合距离。对于BLR分析,发现正确分类百分比在右手掌的a-t距离上最高,成功率为80.5%,紧随其后的是组合abcd-t距离,其对右手掌的分类成功率为80.0%。本研究得出的结论是,手掌的径向间距在性别上是相当二型的,但只能作为法医调查推断性别的补充工具。由于精度更高,建议使用a和t三半径之间的距离,而不是Badiye及其同事(2019)进行的原始研究中建议的组合abcd-t距离。

Sexual variation in the inter-triradial distance of the palm among Bengali Hindu population of Kolkata, India
Palm prints are one of the most important forensic tools for human identification in medico-legal investigation. Palm prints are often used for forensic sex estimation to narrow down the pool of suspects through a process of elimination. The aim of this study was to test whether a novel approach of sex estimation from palmar inter-triradial distances previously posited by Badiye and colleagues [Journal of Forensic and Legal Medicine, 2019; 65(March):22–26] can be used as a primary tool for forensic sexing. For this study the bilateral palm prints from 200 Bengali Hindu adults (100 male, 100 female) were collected using traditional ink printing method and were analysed. Descriptive statistics were presented in tables and linear discriminant analysis was conducted to estimate the extent of sexual dimorphism in the inter-triradial distances and to find out variables with the strongest sex discriminating potential. Binary logistic regression analysis (BLR) was performed to derive sex estimation equations. Sexual dimorphism has been found to be statistically significant (p< 0.001) using linear discriminant analysis with a sexing accuracy of 79.0 percent for the left and 79.5 percent for the right palm. Distance between a and t triradius has been found to be the most influential on this model followed by the combined abcd-t distance. For the BLR analysis, the correct classification percentage was found to be the highest on the a-t distance of the right palm with a success rate of 80.5 percent which is closely followed by the combined abcd-t distance which has a classification success rate of 80.0 percent for the right palm. The present study has concluded that, inter-triradial distance of the palm is fairly dimorphic sexually but can only be used as a supplementary tool in inference of sex for medico-legal investigation. Due to a higher accuracy, the distance between a and t triradius has been proposed to be used instead of combined abcd-t distance which was suggested in the original study conducted by Badiye and colleagues (2019).
