Multiple validation studies indicate that the Klales et al. (2012) performs well in groups with levels of sexual dimorphism comparable to U.S. whites and blacks with which the method was created. Validation studies in groups with lower levels of pelvic sexual dimorphism indicate that the method performs only fairly (accuracy rates around 75%-85%). In response, population specific equations were developed for use in these groups. Validation and recalibration studies are linked below.
Because of the varying levels of pelvic sexual dimorphism, a global study was conducted that combined both groups with high and low levels of pelvic sexual dimorphism to create a "global equation." This global equation is available here "Worldwide Population Variation in Pelvic Sexual Dimorphism: Validation and Recalibration of the Klales et al. Method" in the journal Forensic Science International.
A free database, MorphoPASSE, is being developed as part of a National Institute of Justice Grant (#2015-DN-BX-K014). Within the program, users can select the original Klales et al. method equation, population specific equations, or the global equation and then can enter the scores of their unknown individual for sex prediction.
