mFI-5 Association with Pulmonary Complications After Lobectomy: 391 Patient Study

A retrospective study of 391 patients undergoing lung resection, with a mean age of 62.17 years and 61.13% male. The data investigates the differential association between the 5-factor modified frailty index (mFI-5) and specific postoperative pulmonary complications. The dataset was authored by Qianying Zheng and last updated on 2026-04 -13.

Use Cases

• Predicting postoperative pulmonary infection risk based on frailty status and patient demographics.
• Analyzing differential associations between frailty and complication types (infection vs. pneumothorax/effusion).
• Building risk stratification models using the mFI-5 score, age, and comorbidity burden.
• Conducting subgroup analyses to examine effect modification by factors like sex and smoking history.

Strengths

• 391 patient records with a mean age of 62.17 ± 8.71 years and sex distribution specified.
• Outcomes are defined using EPCO criteria with thoracic surgery-specific refinements.
• Analysis includes multivariable logistic regression with adjustment for comprehensive confounders.

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 source bias inherent to a single retrospective study.
