“…Papaioannou et al (9) study on the skeletal material of contemporary Greek population and recent study done by Kharuhadetch et al (6) on modern Thai population showed high statistically significant sexual dimorphism of all clavicular variables measured. The same outcomes were observed in many investigations comparing the mean value of clavicular parameters between sexes in other populations, e.g., American (16) , Iranian (17) , Indian (18) , Mexican (19) and Greek (12) . Sexual dimorphic characters of the clavicle bone might have more to do with testosterone and male development than with female muscle activity (20) .…”

Background: Precise sex assessment relies over dimorphic dimensions measuring among unknown human remains is a necessary prerequisite for individuals' identification. Clavicle is a flat short bone appears to be better maintained than long bones. Anthropometric analyses of clavicles to determine the sex are evaluated in different populations with high accuracy. Three-dimensional computed tomography (3D-CT) pictures are an effective technique for this. Objective:The aim of the current study was to study sexual dimorphism of the clavicle, as well as establishment of sex prediction equation among Libyan people by utilizing measurements of the clavicle which obtained from 3D-CT images. Subjects and methods: A total of 50 males and 50 females sexes dimensions were measured from 3D CT scans of the left clavicle: C1, C2 and C3 maximum clavicular length, midshaft circumference, and maximum diameter of the midshaft. C4, C5 and C6 indicated minimum midshaft diameter, maximum sternal end, and acromial end widths, respectively. Results: All the studied measurements in the left clavicle showed a statistical significant increase in males compared to females. C4 was the most single sexually dimorphic dimension of the left clavicle with 90% accuracy. Stepwise discriminant analyses of clavicular variables (C2, C4, and C6) yielded high accuracy at the rate of 99 % (99 % crossvalidated). Conclusion: 3D-CT morphomertric analyses of clavicle provide valuable data for identification of sex in modern Libyan population and can be used in forensic investigations.

“…Correspondingly, environmental influence and different demographic group can reduce predictability from the bone more or less. Comparing mean value of scapular and clavicular parameters of Thai to other populations, e.g., American (Dabbs & Moore-Jansen, 2010), Mexican (Hudson et al, 2016), Iranian (Akhlaghi et al, 2012), Indian (Math et al, 2014), Guatemalan (Frutos, 2002), and Greek (Papaioannou et al, 2012;Koukiasa et al, 2017), mean values for scapular and clavicular parameters were different in each population as Thai population tends to be smaller than others. Therefore, it is important to develop discriminant function equations to determine sex for a specific population, especially in Thai population.…”

“…This could naturally be due to less influence of force exertion on the left side as immensely more people are right-handed. Ungchittrakool & Sinloyma (2018), however, concluded that right side of sample is more accurate which is in controversy in comparison to the study by Math et al (2014) and Koukiasa et al (2017). Still, as explained above, we recommend using the left side of the sample to eradicate confounding influence due to greater force exertion on the right arm and hand.…”

As natural disasters or crimes, precise postmortem identification is needed especially in case of unknown human remains. The aim of the study is to assess sexual dimorphism by formulating new multivariate equations based on scapular and clavicular parameters for a modern Thai population. Eight left scapular and six left clavicular parameters were measured from 278 individuals (124 males and 124 females for training group; and 15 males and 15 females for test group) of a modern Thai population with age ranges from 19 to 101 years. All scapular and clavicular parameters were sexually dimorphic. Direct and stepwise multivariate discriminant function analysis was performed to generate models. Three direct multivariate discriminant functions showed accuracy rates from 91.1c to 92.3 % (cross-validated range from 90.3 % to 91.5 %). Similarly, three stepwise multivariate discriminant functions showed accuracy rates from 90.7 % to 92.7 % (cross-validated range from 90.7 % to 92.7 %). Moreover, the test group showed 86.67 % to 100 % of sex determination accuracy in six discriminant functions. As recommendation for sex determination by using combination of the scapular and clavicular parameters yields statistically high accuracy for sex determination. Therefore, the accuracies of these multivariate discriminant function equations obtained from scapula and clavicle can be applied for forensic sex determination, especially in modern Thais.
