Age-related changes in the sternum can be used to estimate the person's age at death in adult Chinese females.
Criteria for use:
(1) age from 18 to 50 years
(2) Han nationality
Parameters examined in female sternum:
1) lateral projection of sternal manubrium
2) superciliary arch-shaped prominence on the ventral side of sternal manubrium
3) the second costal incisure of sternum and sternal synchondroses
4) radial stripes on the ventral side of sternum body
5) other costal incisurae of the sternum
6) lower part of the dorsal side of sternum
