Figure 1: Receiver operating characteristic (ROC) curve analysis of PR, VSL, and VAP values and the new model. The areas under the curve (AUC) of these predictors were 0.746, 0.589, 0.612, and 0.789, respectively. PR (%): progressive motility; VSL (μm s−1): straight-line velocity; VAP (μm s−1): average path velocity
