Table 5 Logit model for success of having a viable blastocyst

From: Acrosome reaction and chromatin integrity as additional parameters of semen analysis to predict fertilization and blastocyst rates

Viable embryos ≥40% Beta coefficient (CI)a SE p value
%DFI −0.19 (− 0.37 to − 0.08) 0.05 0.001
Constant 5.11 (2.09–8.51) 1.36 0.000
  1. DFI = DNA fragmentation index. aCI: 95% confidence interval. ROC cutoff = 0.70. AUC = 0.773. Specificity = 68.2%. Sensitivity = 72.3%. Positive predictive value = 82.9%. Negative predictive value = 53.6%. Constant = βo from the logit model (Ln(basal probability of viable embryos ≥40% if %DFI is equal to zero)) n = 69
