Hemoglobin Levels and Diabetic Retinopathy in Chinese Type 2 Diabetes Patients

A 2026 cross-sectional study of 9,215 Chinese patients with type 2 diabetes mellitus, authored by Jinghan Zheng and shared on figshare. It analyzes the association between hemoglobin concentration and diabetic retinopathy prevalence, finding 1,757 (19.1%) participants diagnosed with DR. The data suggests a negative correlation, with higher hemoglobin levels linked to lower DR risk.

Use Cases

• Assessing diabetic retinopathy risk based on hemoglobin levels and demographic covariates
• Training predictive models for DR likelihood using clinical and behavioral variables
• Conducting subgroup analysis on sex-specific associations between hemoglobin and DR
• Validating nonlinear relationships in clinical data using restricted cubic spline models

Strengths

• Includes data from 9,215 patients, providing a substantial sample size
• Reports specific prevalence figures (19.1% DR) and adjusted odds ratios (e.g., OR 0.99 per 1 g/L Hb increase)
• Conducts sensitivity analyses and subgroup assessments to test result robustness

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• The dataset is very small (16.3 KB), indicating limited scope, likely containing summary statistics rather than raw patient records
