Supplementary file 1_Association and incremental predictive value of preoperative AISI and

Ruihua Fan's 2026 study provides data on 412 esophageal squamous cell carcinoma patients who underwent McKeown esophagectomy after neoadjuvant chemoimmunotherapy between January 2019 and December 2025. The dataset focuses on the association between preoperative biomarkers AISI and CALLY and the occurrence of postoperative pulmonary complications within 30 days of surgery. It includes results from logistic regression and model performance analyses.

Use Cases

• Predicting postoperative pulmonary complication risk based on preoperative biomarker levels AISI and CALLY.
• Evaluating the incremental predictive value of combined biomarker models versus clinical variables alone.
• Developing risk stratification tools for patients undergoing esophagectomy after neoadjuvant chemoimmunotherapy.

Strengths

• Includes data from 412 consecutive patients, a substantial cohort for this specific surgical context.
• Study period spans from 2019 to 2025, providing a multi-year view.
• Results include specific model performance metrics, such as an AUC of 0.712 for the final integrated model.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect temporal and procedural bias inherent to a single retrospective study.
