This research tests the accuracy of age-at-death estimation from the sternal end of the fourth rib. Age was estimated using the Işcan and Loth casts and written descriptions. The correlation results indicate that there are significant differences in the observed versus actual ages (r = 0.75329, p < 0.001) and that there are significant interobserver differences. Intraobserver tests showed that no significant differences were found within observers. Results of the rib end analysis compared to the results from the pubic symphyses suggest that the rib performs better than the pubic symphysis in age estimation. The rib ends were sorted based on morphology without prior knowledge of age. Summary statistics were calculated for each new phase, and descriptions were created. A variant form of the rib end was described, and the previously understated feature of bone quality was emphasized.
本研究测试了根据第四肋骨胸骨端估计死亡年龄的准确性。使用伊什坎（Işcan）和洛思（Loth）模型及文字描述来估计年龄。相关性结果表明，观察到的年龄与实际年龄之间存在显著差异（r = 0.75329，p < 0.001），并且观察者之间存在显著差异。观察者内测试表明，在观察者内部未发现显著差异。与耻骨联合的结果相比，肋骨端分析的结果表明，在年龄估计方面，肋骨比耻骨联合表现更好。在不了解年龄的情况下，根据形态对肋骨端进行了分类。计算了每个新阶段的汇总统计数据，并进行了描述。描述了肋骨端的一种变异形式，并强调了此前被低估的骨质特征。
