C-Reactive Protein-to-Albumin Ratio and 6-Month Limb Event Risk in Diabetic Foot Ulcers

A retrospective cohort study of 139 hospitalized patients with diabetic foot ulcers from a regional referral center in Northwest China between January 2020 and January 2025. The dataset, authored by Aihemaitijiang Aihetaier and shared on figshare, evaluates the prognostic value of the C-reactive protein-to-albumin ratio for predicting 6-month major adverse limb events.

Use Cases

• Developing prognostic models for major adverse limb events based on inflammatory and nutritional markers.
• Analyzing the association between ulcer area and clinical outcomes in diabetic foot care.
• Validating the incremental predictive value of the C-reactive protein-to-albumin ratio over conventional clinical variables.
• Training classifiers to stratify patient risk using logistic regression-derived features.

Strengths

• Includes data for 139 patients with complete records from a cohort of 321 screened individuals.
• Model performance was assessed with multiple metrics, including an area under the ROC curve of 0.852.
• The dataset is licensed under CC-BY-4.0, permitting open sharing and adaptation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for certain modeling tasks.
• The study is from a single regional center in Northwest China, which may limit generalizability.
