Nomogram model to predict the risk of moderate to severe ovarian hyperstimulation syndrome of long protocol group in fresh cycle.

ABSTRACT: To explore the risk factors of moderate to severe ovarian hyperstimulation syndrome (Ovarian hyperstimulation syndrome, OHSS) in patients using the early-follicular phase long-acting gonadotropin-releasing hormone agonist long protocol (EFLL) group in fresh cycles, and to establish a nomogram model to predict the risk of moderate to severe OHSS. We retrospectively analyzed clinical data from 4,204 patients who receiving in vitro fertilization/intracytoplasmic sperm injection and embryo transfer (IVF/ICSI-ET) at the Reproductive Medicine Department of the Second Affiliated Hospital of Zhengzhou University from January 2015 to August 2024. A total of 4204 cases using EFLL protocol were included. The clinical cases were randomly divided into a modeling group (2,942 cases) and a verification g
