Table 4. Areas under the curve (AUC) for seminal reactive oxygen species (ROS) levels in neat and washed semen in fertile patients with (Endtz, more than 0 and less than 1 x 106/mL) and without (Endtz, 0) leukocytes in semen*
  Variable   Cutoff value   Sensitivity (%)   Specificity (%)   Accuracy (%)   AUC (%)   95% CI for AUC (%)
  Without leukocytes (Endtz, 0)            
      ROSs in neat semen   0.5   73.3   76.0   75.6   76.4   62.6-90.2
      ROSs in washed semen   10   73.3   68.0   68.9   77   62.6-91.7
  With leukocytes (Endtz, >0 and < 1 x 106/mL)            
      ROSs in neat semen{dagger}   1.25   73.3   66.7   69.6   72.7   60.8-84.7
      ROSs in washed semen{dagger}   51.5   71.9   74.4   70.3   81   70.3-91.6
  *AUC indicates area under the curve; CI, confidence interval.
  {dagger}ROSs are x104 counted photons per minute per 20 x 106 sperm.
