Abstract
Objective: In this study, our aim was to obtain the cut-off values with the “Receiver Operator Characteristic (ROC)” for estimating gender from the hand sizes of young adult female and male individuals, and also to create logistic regression equations.
Material and Method: This study was carried out on 64 healthy young adult volunteers (29 males, 35 females) aged 18-22 years. Hand photos of the volunteers were taken using the Canon 800D camera. Hand length and hand breadth were measured with the “Image J” program. A total of 256 measurements were carried out.
Results: Right hand mean length (in cm) was 17.70 for women and 20.01 for men; The mean breadth of the right hand was found to be 8.10 in women and 9.34 in men. The difference between the right and left sides in terms of hand length in men and both hand length and hand breadth in women was statistically significant p<0.005. The difference between the genders in terms of hand length and breadth values was also statistically significant, p<0.005. Cut-off values (in cm); 18.97 for right hand length, 8.874 for right hand breadth, 19,015 for left hand length, and 8.883 for left hand breadth. Regression equations for estimating gender were obtained from hand length and hand breadth. Among the equations created based on hand length and hand breadth, the equation with the highest probability of correct prediction was the equation based on left hand breadth (R square=0.824, overall true predicted ratio =93.8%).
Conclusion: We believe that the regression formulas obtained from hand morphometric values will be useful for anatomists, forensic medicine specialists and forensic anthropologists.

Genç Erişkinlerde El Anatomisi, Cinsiyet Farklılıkları, ROC Eğrisi Değerleri ve Regresyon Formülleri
Abstract
Amaç: Çalışmamızda genç erişkin kadın ve erkek bireylerin el boyutlarından cinsiyet tahminine yönelik “Receiver Operator Characteristic” analizi ile cut-off değerlerinin (kesme-değerlerinin) elde edilmesi ve logistic regresyon denklemlerinin oluşturulması amaçlanmıştır.
Gereç ve Yöntem: Çalışma, sağlıklı 18-22 yaş aralığında, 64 genç erişkin gönüllü üzerinde (29 erkek, 35 kadın) gerçekleştirildi. Gönüllülerin el fotoğrafları Canon 800D fotoğraf makinesi kullanılarak çekildi. Standardizasyon için fotoğraflamadan önce milimetrik cetvel kullanıldı. El uzunluğu ve el genişliği “Image J” programı ile ölçüldü. Toplamda 128 elde ölçüm yapıldı.
Bulgular: Sağ el ortalama uzunluğu (cm) kadınlarda 17,70, erkeklerde 20,01; sağ el ortalama genişliği kadınlarda 8,10, erkeklerde 9,34 olarak bulundu. Her iki cinsiyette de el uzunluğu değerleri ile el genişliği değerleri arasında orta düzeyde pozitif korelasyon tespit edildi. Erkeklerde el uzunluğu, kadınlarda hem el uzunluğu hem de el genişliği bakımından sağ ve sol taraflar arasındaki fark, istatistiksel olarak anlamlıydı p<0,005. El uzunluk ve genişlik değerleri açısından cinsiyetler arasındaki fark istatistiksel olarak anlamlıydı p<0,005. Kesmedeğerleri (cm); sağ el uzunluğu için 18,977, sağ el genişliği için 8,874, sol el uzunluğu için 19,015 sol el genişliği için 8,883 olarak saptandı. El uzunluğu ve el genişliğine bağlı oluşturulan denklemler içerisinde doğru tahmin ihtimali en yüksek olan denklem sol el genişliğine bağlı oluşturulan denklemdi (R2=0,824, Genel doğru tahmin oranı %93,8).
Sonuç: El morfometrik değerlerinden elde edilen regresyon formüllerinin anatomistler, adli tıp uzmanları ve adli antropologlar açısından faydalı olacağı kanaatindeyiz.
