Cox proportional hazards analysis
After adjustment for confounding factors including age, previous
abortion history, benign ovarian cyst, management and endometriosis, cox
proportional hazards analysis revealed that the patients’ age from 20 to
33 years old (AHR = 2.24, 95% CI 1.13 - 4.44), the history of previous
abortion (AHR = 1.7, 95% CI 1.05 - 2.82), salpingectomy (AHR = 2.04,
95% CI 1.24 - 3.34), and a combined myomectomy for concurrent leiomyoma
(AHR = 2.55, 95% CI 1.22 - 5.33) were positively correlated to live
birth (Table S4).
