Estimation of sex from the metric assessment of digital hand radiographs in a Western Australian population

- Hand-bones are sexually dimorphic in a Western Australian population; male mean > female mean.
- Maximum length of MC3 has the largest mean sex difference between males and females (5.77 mm).
- The most sexually dimorphic measurement is the base width of PP2 (F = 363.88; P < 0.001).
- The highest cross-validated accuracy is achieved using base width of PP5 (85.3%; sex bias −4.0%).
- Stepwise DFA (8 variables) resulted in a cross-validated accuracy of 91.00% (sex bias −6.00%).
