Assisted Reproductive Technology Outcomes for 4,632 Cycles Under Constant Dosage

A retrospective, self-controlled study of 4,632 patients who underwent two consecutive assisted reproductive technology cycles between January 2010 and December 2025. The research, authored by Jie Gao and shared via figshare, evaluates the impact of phenotype-driven protocol switching on cumulative live birth rates while keeping gonadotropin dosages constant.

Use Cases

• Compare the efficacy of different ART protocol switching strategies based on patient phenotype.
• Analyze the relationship between protocol changes and oocyte retrieval outcomes mentioned in the description.
• Model predictors of cumulative live birth rate using multivariable logistic regression on clinical trial data.
• Investigate the effect of age and anti-Müllerian hormone levels on ART success rates.

Strengths

• Dataset covers 4,632 patient cycles, providing a substantial sample size.
• Study period spans 15 years from 2010 to 2025.
• Analysis includes four distinct patient pathways with specific sample sizes (e.g., Long-to-Antagonist n=1,412).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is presented in a PDF report format, which may require extraction to be used for analysis.
