Test of an alternative method for determining sex from the os coxae: applications for modern Americans.
A recently proposed method for determining sex from the os coxae reports a 98% success rate using European collections. The purposes of the present study are to (1) evaluate the success rate of this proposed method using modern American os coxae from different population subgroups; (2) compare the success rate of the new method with that obtained using traditional techniques; and (3) determine replicability of the new method and interobserver error. Eight hundred and seventy-six adult left os coxae were independently evaluated by both authors. Summary statistics for sex classifications were calculated for the total sample and for a random sample of 400 individuals. The impact of sex and ancestry on the success of each method was calculated on the random sample using Pearson's chi2 values. Results demonstrate that for modern American os coxae, neither sex nor race have a significant impact on the success rate for either the new or traditional methods (p < 0.01). Additionally, the success rate of the new method is comparable with that obtained using traditional techniques. Finally, interobserver error using the new method for overall sex determination is low.
