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

Table 5 Logit model for success of having a viable blastocyst

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

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
