Table 3_Association between systemic immune-inflammation index(SII) and all-cause and card

A retrospective cohort study of 1,084 heart failure patients hospitalized between January 2022 and June 2023, with follow-up until July 2025. The dataset, authored by Junlan Zhang and shared under CC-BY-4.0, analyzes the association between the systemic immune-inflammation index (SII) and all-cause and cardiovascular mortality.

Use Cases

• Predicting all-cause mortality risk in heart failure patients based on the systemic immune-inflammation index.
• Conducting subgroup analysis to examine effect modification by smoking status.
• Performing mediation analysis to quantify the role of NT-proBNP and left ventricular ejection fraction (LVEF) in the SII-mortality association.

Strengths

• Dataset includes 1,084 patient records from a defined cohort.
• Follow-up period spans from January 2022 to July 2025, providing longitudinal outcomes.
• Analysis includes multiple statistical methods: Cox models, restricted cubic splines, and mediation analysis.

Limitations

• Row count and column-level documentation are unknown, limiting suitability assessment.
• The file is a 14.1 KB DOCX document, suggesting the primary data may be embedded in a manuscript table rather than a standalone structured file.
• Cardiovascular mortality analysis had limited statistical power due to only 60 events.
