- ARIC = Acrosome response to an ionophore challenge, a95% confidence interval. ROC cutoff = 0.65. AUC = 803. Sensitivity = 63.2%. Specificity = 80.6%. Positive predictive value = 80%. Negative predictive value = 64.1%. n = 69. Constant = βo from the logit model (Ln(basal probability of Fertilization ≥60% if ARIC and % morphology are equal to zero))
