Figure 2. Classification Performance of the Main Latent Mediation Model.

The orange receiver operating characteristic curve represents the classification performance of the latent mediator model. The blue receiver operating characteristic curve represents the classification performance of a simple regression of the BPD borderline personality disorder variable on the early life adversity variable, which did not include the latent mediator of the reproduction/maintenance trade-off. For sensitivity, borderline personality disorder was present when present. For specificity, borderline personality disorder was absent when absent. AUC indicates area under the curve.
