[Stature Estimation for Sichuan Han Female Based on Whole-spine X-ray Photo- graphy]

Area of Science:

• Forensic Anthropology
• Medical Imaging
• Biometrics

Background:

• Accurate stature estimation is crucial in forensic and clinical settings.
• Previous methods for stature estimation have limitations.
• Developing population-specific regression models is essential.

Purpose of the Study:

• To develop regression models for stature estimation in Sichuan Han females.
• To utilize total vertebral column length from whole-spine X-rays for this purpose.
• To assess the accuracy of these models.

Main Methods:

• Collected whole-spine frontal and lateral X-rays from 200 Sichuan Han females.
• Measured total vertebral column length from X-ray films.
• Applied linear regression analysis to establish stature estimation models.
• Validated the models using an independent sample set.

Main Results:

• Total vertebral column length demonstrated a strong correlation with stature.
• Lateral X-ray measurements yielded the highest correlation coefficients.
• Established linear regression models were statistically significant (P<0.05).
• The model using lateral total vertebral column length showed superior accuracy.

Conclusions:

• Total vertebral column length is a reliable indicator for stature estimation.
• Lateral X-ray measurements offer the highest accuracy for stature prediction in this population.
• The developed regression models provide an accurate method for stature estimation in Sichuan Han females.
