The aim of this study was to test the reliability of Osborne et al. (2004) [8] age estimation based on the iliac auricular surface of the ilium. We selected 172 skeletons with documented sex and age-at-death and established six uniformly distributed age intervals for analysis. ANOVA was employed to assess the association of the documented age with sex and the auricular surface classification. We employed Bonferroni post-hoc tests to find any statistical differences across documented ages within each phase of Osborne's criteria. While the ANOVA showed a significant association between the documented age and the auricular surface classification, post-hoc tests found that phases 2 and 3 were the only consecutive phases with significant differences. We argue that a lack of statistical significance between consecutive phases undermines the reliability of this method for forensic purposes especially in middle adults. It may be possible that the collapse of intermediate phases would increase the accuracy of this method.
本研究的目的是检验奥斯本等人（2004年）[8]基于髂骨耳状面进行年龄估计的可靠性。我们选择了172具具有记录在案的性别和死亡年龄的骨骼，并建立了六个均匀分布的年龄区间进行分析。采用方差分析来评估记录在案的年龄与性别以及耳状面分类之间的关联。我们采用邦费罗尼事后检验来查找奥斯本案标准各阶段中记录在案的年龄之间的任何统计学差异。虽然方差分析显示记录在案的年龄与耳状面分类之间存在显著关联，但事后检验发现，第2阶段和第3阶段是仅有的具有显著差异的连续阶段。我们认为，连续阶段之间缺乏统计学显著性会削弱该方法在法医鉴定中的可靠性，尤其是在中年成年人中。中间阶段的崩溃可能会提高该方法的准确性。
