Data Sheet 1_Predictive value of the C-reactive protein-to-lymphocyte ratio for prognosis

Data from the MIMIC-IV database for 1,605 patients diagnosed with both congestive heart failure (CHF) and acute kidney injury (AKI). The dataset was used to investigate the prognostic value of the C-reactive protein-to-lymphocyte ratio (CLR) for 30-day and 365-day all-cause mortality. The data was uploaded by Supei Yin on May 19, 2026.

Use Cases

• Predicting short-term (30-day) mortality in CHF-AKI patients based on the C-reactive protein-to-lymphocyte ratio.
• Predicting long-term (365-day) mortality in CHF-AKI patients based on the C-reactive protein-to-lymphocyte ratio.
• Conducting subgroup analyses to identify effect modifiers in the relationship between CLR and mortality.
• Evaluating the discriminative ability of a biomarker ratio for clinical outcomes using ROC curve analysis.

Strengths

• Contains data for 1,605 patients, a specific high-risk clinical cohort.
• Analysis includes multivariable adjustment and tests for non-linear relationships using restricted cubic splines.
• Results show statistically significant hazard ratios for mortality across CLR quartiles, with AUC values of 0.713 and 0.675 for 30-day and 365-day mortality, respectively.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• The dataset is stored as a 1.3 MB PDF, which may require extraction to access underlying tabular data.
• Description metadata is limited; actual data quality requires manual inspection after download.
