The indicators proposed by İşcan et al. (1984) are said to reflect age changes that occur in the sternal end of the fourth rib. These indicators have been used to estimate age-at-death in adult skeletal samples. However, Isçan et al. developed their methods using a forensic sample from Florida (U.S.A.). In order to test the reproducibility of those methods we evaluate its accuracy for the fourth ribs by applying it to a sample of known age and sex but of different biological affinity: modern males from Mexico City. We found that the method developed by İşcan et al. underestimates age-at-death in the Mexican sample.
伊斯坎等人（1984 年）提出的指标据称反映了第四肋骨胸骨端发生的年龄变化。这些指标已被用于估计成人骨骼样本的死亡年龄。然而，伊斯坎等人使用的是来自美国佛罗里达州的法医样本开发他们的方法。为了测试这些方法的重现性，我们将其应用于具有不同生物学亲缘关系的已知年龄和性别的墨西哥城现代男性的第四肋骨样本，以评估其准确性。我们发现，伊斯坎等人开发的方法低估了墨西哥样本的死亡年龄。
