Serum Progesterone and Pregnancy Outcomes in POSEIDON Group 1 Patients

A retrospective cohort study of 402 patients undergoing embryo transfer at Yantai Yuhuangding Hospital between 2016 and 2023. It measures serum progesterone and estradiol levels on the day of transfer to analyze their association with clinical pregnancy rates. The dataset was published by Xin Wang under a CC-BY-4.0 license.

Use Cases

• Predicting clinical pregnancy likelihood based on serum progesterone levels on embryo transfer day.
• Investigating the interaction effect between body mass index (BMI) and progesterone on pregnancy outcomes.
• Developing stratified patient care models using hormone level percentiles.
• Validating the POSEIDON patient classification criteria with real-world clinical data.

Strengths

• Includes 402 patient records from a single-center study.
• Covers a 7-year time range from January 2016 to December 2023.
• Analysis includes multivariate logistic regression and sensitivity analysis for robustness.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to a single hospital in Yantai.
