<p>Definite ectopic pregnancy (dEP: n = 17), probable ectopic pregnancy (pEP: n = 8), definite viable intrauterine pregnancy (dVIUP: n = 28), definite nonviable intrauterine pregnancy (dNVIUP: n = 26), spontaneously resolving PUL (srPUL: n = 27), treated persistent PUL (tpPUL: n = 3) and not pregnant (NP: n = 11). A ROC curve was generated (‘ROC of ADAM12’) to compare serum ADAM12 concentrations in patients with a dEP versus all other outcomes. The analysis was repeated (‘ROC of ADAM12 -PUL Data’) after ‘ambiguous’ pregnancy outcomes (srPUL, tpPUL and pEP) were excluded.</p
