Cohen’s kappa coefficient showing the level of agreement between two methods used to identify females and males with lower Ct.Ar. The two methods include comparing individual values to group averages versus robustness tertile-specific averages. Agreement outcomes are shown when lower Ct.Ar is defined as individuals having the lowest 50%, 33%, or 25% of Ct.Ar values for the group. The randomized-tertile data are shown for the lower 33% of Ct.Ar values for comparison to illustrate that the process of sorting individuals into tertiles did not affect the agreement. The midshaft structural data are the average of the 40, 50 and 60% sites.
