Progesterone and hCG in expectant management success in tubal ectopic pregnancy: retrospective single-centre cohort study

The study was a hypothesis-generating exploratory analysis from a single centre, aiming to address the clinical dilemma of detecting early tubal ectopic pregnancies that may resolve spontaneously. Serum progesterone levels were assessed for association with management outcome, and receiver operating characteristic (ROC) analysis was used to evaluate predictive value. With 91 cases, the findings could help refine selection criteria for expectant management and reduce unnecessary interventions. As a retrospective cohort, the results warrant validation in prospective studies before clinical implementation.
