Frozen Embryo Transfer Outcomes for Day-6 Blastocysts, 2021-2024

Ruiqiong Zhou's study on figshare analyzes 2,058 single frozen–thawed day-6 blastocyst transfers from August 2021 to August 2024. The research investigates the interaction between progesterone exposure duration and blastocyst expansion stage on live birth rates. The dataset likely contains clinical variables and outcomes from this retrospective cohort study.

Use Cases

• Modeling optimal progesterone timing for embryo transfer based on blastocyst expansion stage.
• Training classifiers to predict live birth outcomes from clinical protocol and embryo morphology data.
• Conducting subgroup analysis to identify patient-specific factors influencing fertility treatment success.

Strengths

• Dataset is based on a specific cohort of 2,058 women undergoing a single treatment protocol.
• Study period is clearly defined from August 2021 to August 2024.
• Results show statistically significant interaction effects (P < 0.01) between key variables.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a single retrospective study and may reflect specific institutional practices.
