Table 4_Preoperative low Geriatric Nutritional Risk Index increases intensive care unit ad

Wei-De Lin published a retrospective cohort study analyzing 9,045 gastrointestinal tumor surgery patients from the INSPIRE database. The research investigates the relationship between preoperative Geriatric Nutritional Risk Index (GNRI) scores and postoperative ICU admission risk, identifying a key threshold at GNRI=89. The dataset was last updated on 2026-05-28.

Use Cases

• Predicting ICU admission risk based on preoperative Geriatric Nutritional Risk Index scores.
• Identifying patient subgroups with severe nutritional risk (GNRI < 82) for targeted interventions.
• Validating non-linear relationships between nutritional markers and surgical outcomes.
• Conducting sensitivity analyses on clinical risk factors using multivariable logistic regression.

Strengths

• Analysis is based on a cohort of 9,045 patients, providing a substantial sample size.
• The study employs multivariable logistic regression with stepwise confounder adjustment and sensitivity analyses to verify result robustness.
• A clinically meaningful risk stratification (GNRI < 82) and a key non-linear threshold (GNRI=89) are identified.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• The dataset is very small (16.6 KB), suggesting it contains summary or analysis results rather than raw patient records.
• Freshness should be verified as the last update date is in the future (2026-05-28).
