Table 4 Performance of the OmcB Ct ELISA relative to the MIF test results.

From: Evaluation of an in silico predicted specific and immunogenic antigen from the OmcB protein for the serodiagnosis of Chlamydia trachomatis infections

  Concordance (%) Sensitivity (%) Specificity (%) PPVa (%) NPVb (%)
OmcB Ct ELISA/MIF 72.7 (259/356) 23.9 (26/109) 94.3 (233/247) 65.0 73.7
  1. a: PPV, positive predictive value, b: NPV, negative predictive value. For comparison of the OmcB Ct ELISA test relative to the MIF assay, sensitivity, specificity, PPV, and NPV were calculated by using two-by-two tables.
