Study population
Firstly, we conducted a prospective observational study of a cohort of 761 infertile women who underwent reproductive surgery and delivered at the Division of Obstetrics and Gynecology, University Medical Centre Ljubljana, Slovenia, from 1st July 2012 to 31st December 2015. Further on, a historical case-control study for evaluating preterm delivery as a reproductive surgery treatment-related side effect, a control group was selected among fertile women who delivered in Slovenia in the same period. In Slovenia, 99.9% of deliveries are in-hospital.
There was no patient and public involvement in the study.
