Supplementary file 1_Association between the albumin-to-lymphocyte ratio and short-term mo

7,591 pediatric intensive care unit (PICU) patient records from a single-center database spanning 2010 to 2019. The data was used to investigate the prognostic value of the albumin-to-lymphocyte ratio (ALR) for 28-day mortality, achieving an AUC of 0.835 with an XGBoost model. Author Kai Chen published the supporting document for this retrospective cohort study on figshare.

Use Cases

• Predicting 28-day all-cause mortality in PICU patients based on early clinical biomarkers.
• Evaluating the non-linear association between the albumin-to-lymphocyte ratio and patient survival risk.
• Benchmarking machine learning models like XGBoost for clinical risk stratification tasks.
• Conducting subgroup analyses to assess the robustness of biomarker associations across different patient strata.

Strengths

• Contains 7,591 patient records from a decade-long period (2010-2019).
• Study reports a strong predictive performance with an XGBoost model AUC of 0.835.
• Analysis includes adjusted Cox models and restricted cubic splines to explore non-linear relationships.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is from a single-center study, which may limit generalizability.
• The primary data file is a 956.1 KB DOCX document, which likely contains analysis and results rather than the raw dataset.
