Khanpetch 2012
Definition
A South-East Asian long-bone sex estimation study by Khanpetch and colleagues providing population-specific discriminant functions and cut-offs for Thai and South-East Asian populations, frequently cited alongside Indian data because of shared gracile body build characteristics.
