Objective:

To evaluate the effectiveness of a multivariable model combining skeletal maturation and bone length for forensic age estimation compared to traditional methods.

Key Findings:
  • The combined model showed an area under the curve of 0.94 and overall accuracy of 87%.
  • Sensitivity for identifying adults was 91.4%, with specificity at 80.1%.
  • Single-variable models performed worse, with the MCE-only model not matching the combined approach.
Interpretation:

The combined model provides a more accurate assessment of age, particularly for identifying individuals at the legal age of 18, compared to traditional single-indicator methods.

Limitations:
  • Study population limited to Italian patients.
  • Use of a single anatomical region may lead to wider prediction ranges.
Conclusion:

Transitioning from rigid cut-offs to statistical modeling enhances age estimation accuracy and reduces false negatives in forensic assessments.
