    A multivariable model combining skeletal maturation, clavicle length, and sex improves forensic age estimation accuracy.

  • 2

    The combined model achieved an area under the curve of 0.94 and an overall accuracy of 87% in age classification.

  • 3

    Sensitivity and specificity for identifying adults were 91.4% and 80.1%, outperforming traditional single-variable methods.

  • 4

    Clavicle length was a significant age predictor for ages 10 to 15 but not for ages 16 to 20, crucial for legal adulthood.

  • 5

    The study supports statistical modeling over rigid thresholds for better risk assessment in forensic age estimation.
