Validation of the DSP2 Tool in a Contemporary Identified Skeletal Collection from Northeastern Brazil

Abstract

The Diagnose Sexuelle Probabiliste v.2 (DSP2) is an accurate tool used for estimating the sex of an individual through the os coxae. The goal of this study was to verify the applicability of the DSP2 tool in a skeletal sample from Northeastern Brazil and to attest for its precision, accuracy, and reliability. The sample was composed of 301 os coxae from the Center for Studies in Forensic Anthropology of the College of Odontology from the University of Pernambuco, in Pernambuco, Brazil. The results reveal that it was possible to correctly estimate the sex of 83.7% of the total sample. The error rate was 0.4%, and the percentage of undetermined individuals varied according to the combination of measurements used. The results demonstrated a high index of accuracy and a low error rate, indicating that DSP2 is a reliable tool for sex estimation applied to this studied Brazilian population.
