Table 1_Association of preoperative prognostic nutritional index with postoperative deliri

Xiaoya Hong's study, last updated May 2026, analyzes data from 354 gastric cancer patients who underwent gastrectomy between January 2023 and December 2024. It investigates the prognostic nutritional index (PNI) and other clinical factors as predictors for postoperative delirium (POD). The dataset likely contains patient demographics, laboratory values, and surgical outcomes used in the logistic regression analysis.

Use Cases

• Predicting postoperative delirium risk based on preoperative nutritional and immune status markers.
• Identifying independent clinical risk factors for surgical complications using logistic regression.
• Evaluating the predictive performance of the prognostic nutritional index via ROC curve analysis.
• Studying associations between patient age, ASA score, and hospital stay duration with delirium outcomes.

Strengths

• Dataset is derived from a study of 354 patient records, providing a substantive clinical sample.
• Analysis includes specific predictive performance metrics, such as an AUC of 0.780 for PNI.
• Clear temporal coverage from January 2023 to December 2024.
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

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