Subject group: 70 adult Caucasian Europeans
Measurement:
(1) Bone measurements were done with a digital calpier.
(2) The supero-inferior diameter used for the formula was the minimum measurement from the superior to inferior surfaces at the narrowest part of the femoral neck.
score =
= (0.505 * (superoinferior diameter in mm)) - 17.136
Interpretation:
• A score > 0 indicates male gender.
• A score < 0 indicates female gender.
Performance:
• 90% of patients were correctly classified.
• The performance depends on factors such as race and generation; the function would not perform as well on older skeletons when nutrition was different.
• A person's stature and proportions would affect the results. A male with short stature and small frame would mark as a female.
The authors studied 2 other skeletal collections:
(1) Hamann-Todd collection
(2) University of New Mexico
score for the Hamann-Todd sample =
= (0.496 * (superinferior diameter)) - 15.163
score for the University of New Mexico sample =
= (0.387 * (superinferior diameter)) - 12.462
