Table 1_Prevalence of malnutrition and its prognostic impact in lung metastasis patients t

A retrospective cohort of 185 patients with pulmonary metastases treated with stereotactic body radiotherapy (SBRT). Nutritional status was assessed using four tools—Nutritional Risk Index (NRI), Controlling Nutritional Status (CONUT), Nutritional Risk Screening 2002 (NRS), and Prognostic Nutritional Index (PNI)—to evaluate their prognostic utility for overall survival. The dataset was created by Yunjie Zhang and last updated on 2026-05-28.

Use Cases

• Comparing the prognostic performance of different nutritional assessment tools (NRI, CONUT, NRS, PNI) based on hazard ratios and prevalence rates.
• Developing an integrated prognostic model for overall survival based on combined nutritional and clinical variables.
• Assessing the prevalence of malnutrition in a specific cohort of lung metastasis patients undergoing SBRT.
• Identifying high-risk patients for targeted nutritional interventions based on risk stratification scores.

Strengths

• Includes data from 185 patients, providing a substantial cohort for analysis.
• Compares four established nutritional assessment tools (NRI, CONUT, NRS, PNI) with reported prevalence rates (65.95% to 79.46%).
• Reports multivariable analysis results, identifying CONUT and NRI as independent prognostic factors with specific hazard ratios (HR = 1.09 and HR = 3.99).
• An integrated model combining nutritional and clinical variables achieved a C-index of 0.681, indicating its predictive performance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• The data is contained in a DOCX file (162.4 KB), which suggests the primary data may be embedded in tables or text rather than a structured data format.
