Table 1_Prevalence and clinical correlates of diabetes in hospitalized heart failure patie

Lingqin Li's retrospective study from Zigong Fourth People’s Hospital includes data from 2,008 adults hospitalized with heart failure, of whom 466 had diabetes. The dataset contains demographic, clinical, hemodynamic, and laboratory variables extracted from first admission records. It was last updated on figshare in April 2026.

Use Cases

• Estimate the prevalence of diabetes in hospitalized heart failure patients based on the reported 23.21% prevalence figure.
• Identify clinical factors associated with diabetes using variables like sex, systolic blood pressure, statin use, WBC count, potassium, and HDL-C.
• Train or validate machine learning models for variable importance ranking, as referenced in the description.
• Conduct sex- and age-stratified analyses to assess heterogeneity in clinical correlates.

Strengths

• Includes 2,008 patient records with 466 confirmed diabetes cases, providing a specific cohort size.
• Contains multiple variable types: demographic, clinical, hemodynamic, and laboratory data.
• Analysis includes multivariable logistic regression, machine learning models, and stratified analyses, suggesting structured underlying data.
• Dataset is openly licensed under CC-BY-4.0.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the underlying data tables is unknown, which may limit suitability assessment.
• Data is sourced from a single hospital in China, which may limit generalizability.
