<p>De-identified Database.</p>

306 adult orthotopic liver transplant recipients who received at least 10 liters of perioperative fluid between 2009 and 2023, forming a single-center retrospective cohort. The dataset, created by Zac Tran and shared under CC-BY-4.0, was used to compare outcomes between recipients of massive (10–<20 L) and ultramassive (≥20 L) transfusion. Propensity score matching was applied to balance recipient, donor, and intraoperative characteristics for analysis.

Use Cases

• Analyzing the association between ultramassive fluid transfusion and short-term mortality based on 90-day survival data.
• Studying long-term patient survival outcomes based on 3-year and overall mortality endpoints.
• Investigating secondary clinical outcomes such as graft failure, acute kidney injury, and hospital length of stay mentioned in the description.
• Applying propensity score matching techniques to observational clinical data for comparative effectiveness research.

Strengths

• Dataset includes 306 patient records from a 14-year time span (2009-2023).
• Analysis employed propensity score matching on 188 patients to balance confounders.
• Study evaluated multiple primary and secondary clinical endpoints, including 90-day, 3-year, and overall mortality.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is from a single center, which may limit generalizability.
• Row count for the full matched/unmatched cohorts is unknown, which may limit suitability assessment.
