چکیده:
Studying the human remains and analyzing demographic problems, sex ratios, and mortality rates in Shahr-e Sokhta
(The Burnt City in Persian) can prove highly valuable in identifying the ancient peoples of the region, thus shedding light on a
significant transitional period between the prehistoric and the historic eras. In this study, a gender-based analysis was conducted on the
anthropometric data extracted from the existing reports on Shahr-e Sokhta III via two statistical methods, namely, the life table method
and the Kaplan-Meier method. Of the 370 studied skeletons, 218 belonged to women and 152 to men. Two statistical survival analysis
methods were used to examine the skeletal remains of men and women over the age of 12. The results (P-value = 0.143) of the Kaplan-
Meier method (using the log-rank test) did not reveal a statically significant difference between age at death distributions obtained
for men and women. However, the life table method (via the Wilcoxon signed-rank test) indicated a statically significant difference
between men and women in terms of age at death distributions (P-value = 0.003). The results of the life table method obtained in this
study are in agreement with those indicated in the reports on Shahr-e Sokhta III. Therefore, we concluded that the contradiction in the
results obtained through the Kaplan-Meier and the life table methods might be due to the different weightings attributed in the log-rank
test and the Wilcoxon test. For this reason, we propose that similar studies be conducted in other ancient sites where cemeteries with
skeletal remains have been unearthed.

Comparing the Determined Age at Death between Men and Women Based on the Human Bones Excavated from Shahr-e Sokhta1 Archaeological Site: A Survival Approach Using Life-Table and Kaplan-Meier Methods Abdolkarim Shadmehr Tarbiat Modares University, Iran Ebrahim Hajizadeh Tarbiat Modares University, Iran Ahmadreza Baghestani Shahid Beheshti University of Medical Sciences, Iran Seyyed Mansour Seyyed Sajjadi Head of Shahr-e sokhta and Dahan-e Gholaman Archaeological Excavations, Iran Received: May 5, 2016 Accepted: December 10, 2016 Studying the human remains and analyzing demographic problems, sex ratios, and mortality rates in Shahr-e Sokhta (The Burnt City in Persian) can prove highly valuable in identifying the ancient peoples of the region, thus shedding light on a significant transitional period between the prehistoric and the historic eras.
In this study, a gender-based analysis was conducted on the anthropometric data extracted from the existing reports on Shahr-e Sokhta III via two statistical methods, namely, the life table method and the Kaplan-Meier method.
However, the life table method (via the Wilcoxon signed-rank test) indicated a statically significant difference between men and women in terms of age at death distributions (P-value = 0.
This study aims to use the life table and the Kaplan- Meier methods to evaluate distribution of age at death, and compare men and women age at death in Shahr-e Sokhta based on the skeletal remains discovered by the Iranian Archaeological Team between 1997 and 2008.
In view of this, the present study used the life table and Kaplan-Meier methods to analyze the age at death (survival rate) distribution in terms of gender of the inhabitants of Shahr-e Sokhta.
