传统的估计死亡时骨龄的方法仅依赖于耻骨联合面，或以非系统的方式结合其他指标。提出了一种多因素方法，该方法使用五个指标（耻骨联合面、耳表面、股骨近端X线片、牙齿磨损和缝线闭合）的主成分加权。通过对来自托德收集的两个样本的年龄进行完全盲法评估，对该方法进行了测试，这些样本经过仔细筛选，以确保所述死亡年龄的准确性。结果表明，多因子方法在偏倚和准确性方面明显优于任何单一指标。这是第一次对死亡年龄指标或系统进行真正的盲态测试，因为测试人群独立于正在测试的系统，并且在测试完成之前，被评估个体的年龄、性别和人种地理来源（以及测试样本的组成）完全未知。古人口的影响进行了讨论。
Traditional methods of estimating skeletal age at death have relied solely on the pubic symphyseal face or on this indicator combined with others in nonsystematic ways. A multifactorial method is presented that uses a principal components weighting of five indicators (pubic symphyseal face, auricular surface, radiographs of proximal femur, dental wear, and suture closure). This method has been tested by completely blind assessment of age in two samples from the Todd collection carefully screened for accuracy of stated age at death. Results show a marked superiority of the multifactorial method over any single indicator with respect to both bias and accuracy. This represents the first truly blind test of an age-at-death indicator or system, as the test populations were independent of the system(s) being tested, and the age, sex, and ethnogeographic origin of the individuals being assessed (as well as the compositions of the test samples with respect to these variables) were completely unknown until the tests were completed. Implications for paleodemography are discussed.
