Hemoglobin Levels and Diabetic Retinopathy in Chinese Type 2 Diabetes Patients

9,215 Chinese patients with type 2 diabetes mellitus were analyzed in a cross-sectional study to evaluate the relationship between hemoglobin concentration and diabetic retinopathy. The dataset includes 1,757 diagnosed DR cases and presents results from multivariable logistic regression and restricted cubic spline models. Jinghan Zheng published the findings on figshare in May 2026.

Use Cases

• Assessing DR risk stratification based on hemoglobin levels mentioned in the description
• Training predictive models for diabetic retinopathy using clinical covariates like Hb tertiles
• Analyzing nonlinear relationships between biomarkers and disease outcomes using RCS models

Strengths

• Includes 9,215 patient records, providing a substantial sample size
• Reports specific statistical results, including adjusted odds ratios (e.g., OR 0.99 per 1 g/L Hb increase) and prevalence figures (19.1% DR)
• Employs advanced analytical methods like restricted cubic spline models to explore nonlinear associations

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to a single Chinese population study
