Supplementary file 2_Association and incremental predictive value of preoperative AISI and

412 consecutive esophageal squamous cell carcinoma patients who underwent McKeown esophagectomy after neoadjuvant chemoimmunotherapy between January 2019 and December 2025. The data, published by Ruihua Fan in April 2026, includes preoperative biomarkers and outcomes to evaluate their predictive value for postoperative pulmonary complications.

Use Cases

• Predicting postoperative pulmonary complication risk based on preoperative inflammatory biomarkers AISI and CALLY.
• Building a combined biomarker-clinical variable model for surgical risk assessment.
• Evaluating the incremental predictive value of biomarker indices over clinical variables alone.
• Conducting sensitivity analysis for clinical associations using propensity score matching.

Strengths

• 412 patient records provide a substantial clinical cohort.
• Analysis includes multiple validation methods: ROC analysis, DeLong testing, calibration, and decision curve analysis.
• Data covers a defined time range from 2019 to 2025.

Limitations

• Row count and column-level documentation are unknown, limiting suitability assessment.
• The dataset is very small at 18.8 KB, indicating limited scope.
• Data may reflect temporal and institutional bias inherent to a single retrospective study.
