Table 1_Predicting the prognosis of breast cancer patients by using nutrition-based index:

A systematic review and meta-analysis of 32 reports comprising 13,120 individuals with breast cancer, evaluating the prognostic utility of the Prognostic Nutritional Index (PNI) and Controlling Nutritional Status (CONUT) score. The analysis, authored by Si Chen and published on figshare in May 2026, synthesized evidence from four major databases up to October 2025. It reports pooled hazard ratios for overall survival and disease-free survival associated with these nutritional indices.

Use Cases

• Assessing the association between Prognostic Nutritional Index (PNI) and overall survival in breast cancer patients based on the meta-analysis results.
• Evaluating the link between Controlling Nutritional Status (CONUT) score and disease-free survival based on the reported hazard ratios.
• Investigating heterogeneity in prognostic evidence for nutrition-based indices using the described subgroup analyses and prediction intervals.

Strengths

• Analysis is based on 32 reports with a total sample of 13,120 individuals, providing a substantial evidence base.
• The review protocol was registered with PROSPERO (CRD420251249070), indicating a structured methodological approach.
• Results include specific pooled effect sizes (e.g., HR=0.49 for PNI and OS) with 95% confidence intervals and measures of heterogeneity (I²).

Limitations

• The dataset is a single 11.4 KB DOCX document; its scope is limited to the review manuscript and does not contain the underlying patient-level data.
• Column-level documentation for any potential supplementary data is absent; field semantics must be inferred from the manuscript text.
• The primary content is a published analysis; it is not a raw dataset suitable for direct machine learning modeling.
